sorry tigerEz, for me it was between BPs and nadims, as already said nadim's team has the specialists but BP has some really good match winners all the way down in warner, marsh (was the best batsmen in the first IPL), pietersen, mccullum, hodge, raina, pollard. that's a pretty ridiculous t20 batting line up. bowling ajmal is excellent, tait is on and off but can rip right through, morkel is pretty decent and razzak can hold it up.
nadim prob has the strongest bowlers with narine and malinga (prob the 2 best, steyn being the next best), de villiers and gayle possibly the 2 best t20 batsmen right now and shakib and afridi the best spin allrounders right now in t20s. but overall BP has much stronger batting and bowling is solid enough.
a bit surprised not to see albie morkel and andre russell, dwayne bravo not a bad t20 player either.
