I Must admit i really don't understand the hype around Moeen Ali. He's got a pretty average first class record, granted he scored runs last year, but they were in Div 2, where the best bowler is David Masters! His bowling may well be useful, but we have an allrounder already, so really he needs to justify his place as a batsman only. and to be honest, i don't think he does.
Regarding Mills, i agree there has been a lot of hype around him, but having seen him bowl a fair bit at Chelmsford, (and make Cookie look even more awkward) he is a very exciting prospect. For now Topley is MILES better, but Mills should have a good future ahead if he gets his head down and works on his skills
