Chances are he is up to it but I don't think that the move to Notts was a good one for him, nor do I think he is quite ready for international cricket just yet.
Why was Notts not a good move? Well, its a goldfish bowl there, and he is not the same aggressive character as some of those, such as Swann and Broad, who have thrived there. He obviously needed to get away from playing in the Second Division, but could perhaps have chosen better where he went to do that.
Why not ready for internaionals? Lack of top class experience combined with lack of confidence hindered him - though it was a tough old time to be asked to debut against the Yarpies last year. He will get there - he has a good cricketing brain and has shown in the biff bash stuff that he is not short of power, which some commentators held against him last Summer.
