I don't think the cupboard is bare by any means; after all, whilst Anderson will probably only have threyears or so left in him, Broad is only in his mid 290s and Finn is younger than that. Bresnan, Onions and Tremlett may not be long term options but they will all by around for at least a couple more years yet and - this is the point that Boycott's answer misses, though I suspect he is aware of it himself - a lot can happen in that time. As far as I can tell, Harris, Woakes and Roland-Jones are all though to be potentially good enough, and all have the time to put on the couple of mph they probably need to function at the top level, whilst there are plenty of young bowlers in the Shires who could make the necessary leap forward - Mills and Dunn have already been mentioned and I would add to that Moin Ashraf, who is raw but has wheels and swings it both ways, the better of the Overton lads at Somerset and two lads who have moved counties and might use that as a chance to kick on - Chris Jordan and Olly Hannon-Dalby.
