good point but u are missing something here.. It is not with the strike rates being better but with the ability these batsmen have exhibited in the past.. kallis is by nature a sober batsmen and if he gets into a situation where he has to score 20-25 runs in an over, he is out of his comfort zones.. Ross has some insane innings to his credit.. like 81 of32 balls, 51 of 24 balls etc etc in previous ipls which have turned matches.. this is what makes him more dangerous than kallis.. I havent seen such innings from kallis..
