It might seem that way but thats just the way he bats imo mate. Like KJ said there are a number of batsman who given the same match situation would of come out and played in a similar fashion. The likes of Gilly, KP, Shewag, Gayle, Iqbal and Slater are/were all very good test match batsman, but they were half the players when they simply tried to bat time. I'd also add that he averages all but 50, so he can't be letting down England all that often.
I don't agree with him, but i can understand his decision to want to get involved in the IPL. He's 32 and maybe has 2-3 years left as a top draw earner in that competition via the auction process, i don't blame him for wanting to cash in like all the other top cricketers have been able to do. He clearly wanted to continue playing 20/20 cricket for England, so he probably thought he'd only miss out on 'possibly' one ODI world cup at the most. It must have come as a shock to him when the ECB held firm and made him quit both of the shorter formats of the game, again a decision that i agree with.
