T20 format is for experienced players – here in gfx below one is list of players who have participating in this IPL.
For batting i have used two indicators -Age and Runs/Inns
For bowling i have used two indicators – Age and Low Eco Rate X Low Strike Rate
Low Eco Rate is also known as Runs per over
Low Strike Rate is also known as Balls per wicket
Hence if a bowler is able to reduce both these indicators than he becomes the most effective bowler for his team!.
