He wasn't a reject, the season he was released he made 32 appearances and scored 5 goals, mostly playing as a support striker or wide man. He just wanted to move because he didn't get on with Neil Warnock (shocker).
I think it's a given that most Championship clubs would be after him, but if we managed it, I can see it going well as he's exactly the type of player Rosenior would look for, he's English, he's experienced (still only 30) and he can score goals. There probably isn't a better bargain going in terms of Championship strikers at the moment.
