Solving the Super Over Situation

New Zealand have an issue with super overs. We play them much more than anyone else, and we're terrible at them.

We have played in 8 super overs in the past 12 years. We have lost 7 of them. There have only been 15 super overs in the history of international cricket. We play them ridiculously often, and we lose them ridiculously often.

Losing 7 out of 8 stops being bad luck, it start being something that needs to be dealt with.

Here's my solution: We play a single day domestic super over tournament on Waitangi Day every year.

We can either let association have a turn to host it, or pick one venue (possibly Whangarei for the proximity to Waitangi) to host it every year.

The day would work with every team playing a super over against every other team, (15 super overs) then semi-finals and a final.

It would take about 7 hours (shorter if there was quick hand overs between matches) - roughly the same as an ODI match, and could have a rugby 7's type festival feeling to it.

I can already hear the critics talking about shortening the game, and "what's next one ball matches" but this is an issue that needs to be addressed.

In most of those matches we should have won in regular time. We didn't generally get to a super over because we did well, and fought back. We almost invariably got into a super over because we were in a position to win the match, and did not manage to seal it.

Having our players playing those sort of pressure situations more often would tell us who is capable of handling that pressure. As such, we would want a variety of players involved. There should therefore be a rule that each bowler can only bowl in two matches, and each batsman can only be one of the three designated batsmen in three matches. That will mean that each team will have to use at least 3 bowlers and 6 batsmen. For the semi and final then they can pick whoever they want.

This seems to be the only option other than just hoping that we get better.

I'd rather do something, than nothing.

Over to you, New Zealand Cricket.

Who should win the NZ cricket awards

I was asked by Tony Veitch to put together some stats for the different awards on offer for the New Zealand Cricket Awards tonight.

I could have just brought up a list of averages, but that's really not the CricketGeek style, so I decided to delve into things a little more closely.

One of the difficult things in cricket statistics is to compare bowling success with batting success. For example, which is better taking 5/84 or scoring 172? We need a device to compare the two disciplines.

I decided to compare each player's year with the historical averages for their position. For example, for batting I compared the batting average with year end batting averages throughout history. I had a cut off of 10 innings, as making a cut off much higher than that excludes too many players, as most teams play less than 10 tests per year. I then compared a player's average to the historical average of averages, and the standard deviation of averages to generate a z-score. (For more on Z-scores, see This NFL blog post)

I used batting average and bowling average for test cricket, as really what we care about is scoring runs and taking wickets. I wasn't totally happy with the results, as there was no advantage for the players who had maintained a high standard over a number of games, rather than just one. (James Neesham, for example, averaged 171 this season, but only over one match).  I first filtered out anyone who hadn't either batted in 10 matches or who had bowled less than 100 overs. Then I multiplied the z-score by the square root of the number of innings that they had applied their skill in, in order to get a fairer list. It only caused a couple of positional changes, but the new lists looked more appropriate.

Here's the test lists.

Player - SkillAverageRanking
LRPL Taylor - batting81.6012.3
BB McCullum - batting52.735.0
TG Southee - bowling20.073.8
TA Boult - bowling22.363.6
KS Williamson - batting47.213.4
BJ Watling - batting42.272.0
N Wagner - bowling30.421.1
CJ Anderson - bowling30.541.0
CJ Anderson - batting32.70-0.3
TA Boult - batting32.25-0.4

I would give the award to Ross Taylor. He scored 816 runs at an average of 81.60. He past 50 in half of his innings. McCullum, Southee, Boult and Williamson all had great years, but Taylor's average really makes his numbers stand out.

Next I looked at the ODI lists.

Here I decided to use the batting and bowling index developed by S Rajesh from Cricinfo (and me separately). Again I compared the players index to the historical data.

Here's the list:

Player - SkillIndexRanking
CJ Anderson - batting 84.4816.1
LRPL Taylor - batting 43.776.9
MJ Guptill - batting 44.226.4
KS Williamson - batting 39.044.7
MJ McClenaghan - bowling 23.871.1
NL McCullum - batting 26.230.9
JDS Neesham - bowling 23.690.8
CJ Anderson - bowling 24.850.7
KD Mills - bowling 25.970.7
L Ronchi - batting 22.93-0.1

Again a batsman takes the title. This, however was not particularly surprising. Anderson was immense with the bat, and generally the games were played on high-scoring pitches, which don't really flatter bowling statistics.

For the T20 award I used batting index, but my own metric for bowling. In a previous post I showed how each wicket worked out to roughly 5 runs in a t20. Accordingly we can take 5 runs off a bowler's total for every wicket they have taken. They then get a modified run rate. I used this to compare the NZ players' years to the historical data. This is a little less relevant, as there is not a lot of historical data (about 1/10 the quantity of test and ODI information) and also New Zealand only played 6 matches, so the sample size is very small.

Here is the list:

Player - SkillIndex/Modified run rateRanking
L Ronchi - batting221.1114.7
BB McCullum - batting101.084.1
AF Milne - bowling2.752.9
AP Devcich - batting73.341.7
C Munro - batting60.041.5
JDS Neesham - bowling5.000.5
JD Ryder - batting44.020.0
NL McCullum - batting42.25-0.1
NL McCullum - bowling5.64-0.3
HD Rutherford - batting40.02-0.3

Luke Ronchi is a bit of a surprise here, but I remember looking up his stats and being surprised as to how effective he has been in t20s recently. During the course of the year he averaged 133 at a strike rate of 166. Those are quite ridiculous numbers.

The last major prize left is the Sir Richard Hadlee Medal, for the best overall. For me that goes to Brendon McCullum. He managed to attract the attention of the whole nation with his 300, and he also captained the side particularly well across all the formats. There would be a fair argument for Taylor and Anderson, but for me, McCullum needs to be acknowledged some how, and that award seems appropriate.

Who would you give the overall award to?

A Statistician's Look at New Zealand Cricket

I’m really a statistics writer. I’m not the first call for any pieces about management styles, off the field behaviour and so on. When I write about cricket I generally write about what happens on the park, and particularly about the results, and what can be found from analysis. However the current situation in New Zealand Cricket is one that is fascinating to me. The current “crisis” seems to be one that has been misunderstood, misreported, over-estimated and entirely avoidable. So I thought I’d take a statistical enquiry type approach to the current situation, and see what came of it.

The statistical enquiry cycle has 5 parts: Problem, Plan, Data, Analysis and Conclusion.

Problem: Why is there an environment in NZC where a breakdown between captain and coach can have catastrophic consequences and be played out in the public domain as appallingly as this one has.

Plan: Look back over the last 6 years of New Zealand Cricket’s history and see if there is a pattern, and anything that might be the reason:

Data: In a statistical enquiry this is where I gather the numbers. Obviously that’s not so relevant in this situation. So instead I went through just over 4000 articles in three different news archives that related to New Zealand Cricket. Here is a time-line of some of the significant events in New Zealand Cricket over the last 6 years. I’ve broken it up into Governance, Management, Leadership and Players; but some of the issues related to more than one category, so they could have fit across more than one. In these situations I picked what I felt was the most appropriate.

Analysis: This is where I normally do some calculations, arrange the data into a nice table, and perhaps draw a graph. None of those things work here, so instead I’ve looked at some of the trends in the stories.

The one constant in New Zealand cricket over the past 6 years has been change. During that time the team has had 5 coaches, at least 11 selectors and at least 16 assistant or specialist coaches. There has been a litany of job titles for people too. General manager of cricket, chairman of selectors, convenor of selectors, national selection manager, high performance manager, performance director, director of cricket selection advisor, batting advisor etc. There have also been 6 captains for the international team (although Kane Williamson was only as an injury replacement and Jamie How was only for a tour match)

There have been a number of quite significant changes in the power balance between the captain and the coach. First there was a confrontation between Bracewell and Fleming. Then Moles and Vettori. Then Hesson and Taylor. The role of the captain has changed a number of times. Vettori was a selector, and for a while was actually the coach as well (although that was only for about 2 weeks while the team was between coaches). However this is not an issue that is limited to New Zealand cricket. There were similar issues in Australia between Warne and Buchanan and most spectacularly in England between Pietersen, Flintoff and a range of coaches.

An interesting story came out in 2009 where Richard Hadlee felt that Fleming had downgraded the role of coach in New Zealand. That balance in power has certainly been an issue.

Likewise there was an issue with player power in Central Districts while Dermot Reeve was coach, and almost one in Auckland not long after Paul Strang took over. In that situation Auckland Cricket acted quickly, brought in someone extra to help sort out the communication and define the roles between the senior players and the coach.

Conclusion: This is not the first time that there has been a power issue between coach and captain in New Zealand Cricket, or in international cricket in general. It is something that has been bubbling under the surface for a while. New Zealand Cricket probably need to do what Auckland did: bring in someone who is respected by both the coaches and the players, get them to work with both groups to define clearly the roles and expectations of the coach and captain. And then stick with it.

There have been so many changes in New Zealand Cricket over the past 6 years, that consistency is probably better than making more changes. However the roles need to be more clearly defined, and there needs to be a third person introduced to make sure that the two are working together correctly. That person may be the manager, or the director of cricket or someone else, but whoever it is needs to get involved before this happens a fourth time.
