Fallon is good enough for League One. Although having said that if he was in a good team that could make him look good (like Mackie at QPR), with a good passing game, he might have a slim chance of Championship play.
He always seemed to be crowded by defenders when he played the targetman last season and this was why he looked so poor at that job, I think he got more stick from most fans for being slow off the mark and not working as much as say, mackie or noone.
As sensible says, why do we care? Good luck to him.
