The IPL’s best bowler & batsman – by our guest expert Aloke Gupte

(my cousin Aloke, possibly an even crazier cricket buff, submitted this by email so here goes…)
This may elicit a fair number of strong opinions - not only in relation to the precise title of the exercise attempted here, but also because  (a) it is essentially a pointless exercise (who really knows if a Porsche is better than a Maserati??) (b) of the more mundane (if you will) "its early days!"
However, such is the lot of a self assigned crick stats tragic (only 1 other fondness for statistics and never appreciated standard deviation et al), that the attempt must be made. So, lets do that - with one simple twist. I am not looking for your view of who will be THE BEST batsman or bowler (or may just be Player) of the IPL or even who currently occupies that spot.
After 4-5 games (4 for all except KKR and Delhi who have played 5), these are the stats for the batsmen and bowlers. I have kept it focused on runs and wickets respectively for now.

Runs
#1 Kallis 264

#2 Sehwag 186
#3 Sachin 176
#4 Bopara 172
#5 Tiwary 169
#6 Gilchrist 149
#7 Hayden 144
#8 Symonds 143
#9 Yusuf 141
#10 Karthik 124


Wickets
#1 Vaas 8 (@6.06!)
#2 Murli 6 (@5.31)
#3 Symonds 6 (@6.53)
#4 Praveen 6
#5 Ishant 6 (@8.65! thanks, Sachin…)
#6 Balaji 5
#7 Maharoof 5
#8 Nannes 5
#9 Mathews 5
#10 Mishra 5
You may ask about why runs/wickets and not strike/economy rates as the key benchmark. No doubt these are very important and manifold so in T20, but I continue to believe that delivering a mountain of runs or wickets is the best thing you can do to for your team. And I suspect that a majority of the leading run scorers or wicket takers will do well in on strike & economy rates as well (there are and will always be exceptions).
This is illustrated by the fact that amongst bowlers who have played >1match so far, the leading 3wicket takers - Vaas (4th), Murli (1st), Symonds (6th) are a force to reckon with on economy rates. The other slots are interestingly taken up by : #2 Kumble (4@5.43), #3 Kartik (4@5.57), #5 [surprise], Yuvraj (3@6.18), #7 Nannes - a wickets top ten man (5@6.55), #8 Zaheer (3@6.57) with Langevedlt and Rohit Sharma bringing up the top 10
For the batsmen it gets tougher - so I am applying a yardstick of atleast 75 runs scored (I know, you could argue for 50). This is how the top 3 run scorers fare: Kallis (13th), Sehwag (2nd), Sachin (9th). The leaders of the pack there are: #1 Gilchrist, #3Uthappa, #4 Yusuf, #5 Dhoni, #6 Hayden, #7 Rayudu, #8 Irfan (who is the 11th highest scorer), #10 Tiwary. A decent overlap! So you could argue that Kallis can certainly not be the best (1st & 13th) when compared to Sehwag (2nd & 2nd), but then it depends on sheer volume of runs scored and effectiveness for the team. Despite Sehwag's rapid run making, DD are 6th as against Kallis' RCB who are top of the league!
So the question is how will this all play out as the tournament progresses? Will Kallis retain his lead and make up a few places on speed? who will have the purple cap - Vaas? Murli? or Kumble who isnt even in the top 10 but is close with a great eco rate?
The Ask: how will these lists look after 8-9 games each? Based on form, who they are going to play, at what grounds, team changes (i.e. is there an incoming McCullum or KP going to usurp a place??).
