Only if you are blind. Firman wasn't an adaptable player and he couldn't develop his game. Head's injuries have been worse but he had few such problems. Work ethic is one area that would have helped Head.
Injury may have stopped Firman progressing as far as he could have, but he was likely to go from club to club because he couldn't put a game plan into effect ... unless that game plan said run at inopportune times, kick long but rarely keep pressure up on the opposition and do no organising of the team.
Firman had the goods - he had the physical game to be a long-term rep player. Couldn't put a game plan into effect? Pfft. Please... Now I've heard it all. He did no organising? He was what? 22 when he broke his leg? He was sharing the running of a team that had a lot more experience than the current team, and he was starting to gain the team's respect.
I also think he impressed enough reasonable judges to assume he at least had a long first-grade future ahead of him.
He may not have been the most mentally-resilient character, but to say he couldn't put a game plan into effect is borderline geniused.
Get some idea, or let old posts die...
