Consistency and Aggression Index for IPL 2012

Here is my simple way of calculating Consistency and Aggression in IPL

1.       Consistency Index = (TOTAL RUNS/ABS(HIGH SCORE – AVERAGE)) + 10 * No. of 100’s + 5* No. of 50’s + 1* No. of Not outs

2.       Aggression Factor = (%RUNS IN BOUNDARIES) *((100-Strike Rate)/10)

Note: They do not include the IPL 2012 finals between CSK and KKR.

There are 45 players with consistency index of >10. The list could be shortened to 14 if consistency of 25 was made as the par. Consistency of 25 would literally put the player in the most desired top/middle order batsman. The only team to have two batsmen in top 10 of the consistency index is Deccan Chargers – ironically the team to finish on the bottom of IPL 2012. How DC didn’t make it to play off is a totally new topic.

Although consistency is a preferred index it cannot stand alone as players ability as match winner. For example we have Saurav Ganguly with consistency index of 10. Having played almost all the matches this season he has been consistent in the amount of runs he scored. However, he didn’t influence the result of any game in particular. This presents us with a problem, that a consistent player though desired may not be a match winner. Consequently, we need another parameter that in conjunction with consistency index can actually be a representation of player’s ability to be a match winner.

I termed it as “Aggression Index”. In the contest of bat and ball, in the context of T20, we all are waiting for is for the batsman to attack. In Simple terms aggression in the shortest format of the game is ability to score boundaries very frequently.  Aggression factor of >10 clearly indicates a feared batsman capable of scoring at more than run at a ball and punishing bad balls.

Case Study 1: Chris Gayle

The one batsman that is both consistent and aggressive. You really don’t need my table to evaluate his tactics. He is perhaps most consistently destructive batsman in the shorter format of the game. A brief glance at previous two IPL’s will reveal the force he was in the RCB’s wins. With consistency factor and aggression factor of about 50, he is perhaps the most prized batsman in IPL.

Case Study 2: Dwayne Bravo

CF: >50; AF: >20. Success of CSK in crucial matches all boiled down to this match winner. Let it be last over heroics when chasing, brief hurry of runs while batting first; Bravo was the player that stood up. The fact that he didn’t get to bat in the final speaks volumes about CSK batting unit clicking in that match. Bravo’s unique ability comes from batting with the tail and ability to hold one side even when team mates are falling on the other side. And count in his ability to bowl, you have a definite match winner here. So sad to see MI had to let him go for Pollard.

Case Study 3: Dave Warner

CF: < 10; AF: > 20. Dave warner as you can see is a hit or miss. Though very aggressive he lacks consistency. The fact that he even has CF close to 10 is coz of the hundred (which is a significant achievement in T20). Given he was playing with Sehwag at the other end makes it a lot different. Sehwag is consistent and aggressive, while DW is aggressive. This combination should have been ideal for DD’s walk to the final, till they decided to give the match away to KKR and then to CSK’s brilliance.
