It's a shame as we'll probably never know on a few of them - the likes of Sims, Hesketh, Reed, Gallagher were largely ignored over the last few years. Would have been interesting to see how well they would have developed if given a chance and be trusted like Ralph seems to have given the newer crop.
You're right though - it's probably too late for some of them and we'll end of having to sell them on to free up squad space.
