It's a wonderful thing hindsight. All anyone can do, is what they think will work out best at the time, and no doubt Grant Hall did that.
Either way, making a career for yourself, as a professional footballer, you are never going to do too badly.
Conversely, who's to say that had he elected to stay at the Albion, whether he would have been able to get into the team?
Certainly now, three years on, with the likes of Greer, Dunk, Hunemaier, and Goldson at the club, I don't think he would have stood a chance.
