I am one of those who is optimistic about Mills. He's clearly got the skillset and the aptitude - if only he weren't made of glass.
Hopefully off the back of a decent, full pre-season, and carrying no injuries into the season we may finally see the best of him, and a return on investment. It must have been a three year deal off the bat, because given his record I can't see us having extended a 2+1, for example.
He was, IMO, always seen as the replacement for Jimmy, and was to be eased in to take the load off him. That didn't happen.
Time for him to deliver.
