Big question for me - and this shows up my cricketing biases, but what the hell - is can he do it in the Test team?
We've been crying out for a real pace bowler, especially away from home. Well, now we seem to have found one.....but he's only ever played 28 first class matches. Can he keep up that pace and hostility for 15-20 overs over a whole day?
The rest of our seamers will be effective in English conditions, so he may not be absolutely vital in the Ashes. But it's hard to imagine us winning in South Africa without him (or someone like him.....and I don't think we have anyone else like him!)
