Where all your arguments fall down Rover6, is that you apply that logic to all the academy lads. Why pick Andy Taylor out now, - because he's just won the Tranmere Rovers young player of the year. - Not POTY, because he isn't even Tranmere Rovers best player, - but young POTY! Not exactly compulsive evidence of him being good enough to play at Premier league level.
The real truth that you ignore, is that Andy Taylor isn't good enough to play against the best teams in the land. One more point, you say that he might have been a better player if he'd been given a few appearances for rovers first team. Well he's getting first team football at Tranmere, so has he improved enough to get a transfer into a Prem club? Obviously not, why not?
