Hope not, he's not good enough and is a liability
You've been proved comfortably wrong on this over past 2 years.
I don't think he has, to be honest. At least not 'comfortably'. Adam is JUST about good enough for a team in the top half of this league, not 'comfortably' so. Worth retaining as 3rd / 4th choice, but absolutely not good enough to be first choice. the imporovement once Upson arrived last year was plain to see.
As for the liability part - well, he CAN be.
