Buttler would probably average better if the top order didnt keep collapsing. look at the aussies first innings this last time out..those late order batsmen could fire away against a tired blowing attack with little pressure on them. When a number 6 or 7 comes in with 100 - 130 on the board (as it often is with this England team) it's a different game than if its 300-350. Sort out the top order and the rest will look after itself more or less.
Aye I think he would do bit better, I dont wanna defend him too much, he has just pretty reasonable IMO, and his keeping has been fine until recently
The whole thing, all aspects of the game, bowling, selection, catching etc, is all under pressure and making mistakes as they know they wont score many runs, you can just tell they are so tense.
