I don't think Jimmy has that long, kinda expect him to go after the Ashes this winter. Starting to break down too often (been such a relief that he's been as reliable as he has been after his injury riddled start to his career), he's not the bowler he was already, and I think the only reason it's not nailed on for after the Ashes is due to the paucity of bowlers who have done anything at test level for England.
Worried about Broad tbh - he should be good for another 2-3 years, but he takes so long to come back from injury that I feel he's just not going to last long as a test bowler into his 30s.
So glad we picked Dawson. So glad.
