Since 2000, off the top of my head we've had a hand in Luke Joyce, Magno Vieira, Phil Edwards, Tim Chow, Thomas Powell, Jack Sampson, Chris Sang and perhaps one or two others who have slipped my mind, apart from the obvious one (Baines). Now I'm not saying that all of those would have made the grade here, but a few of them have crossed our paths now and again and I can't help wonder with a little more faith how they may have done in the end.
C_Latic hits the nail on the head. It was something I alluded to when I was looking over the business model - it is costing us money. Pretty much all of those players left for nothing, with the exception of Baines and Chow, the latter going for a nominal fee. However, I'd rather see a few players a season offloaded for £50k-£100k and one or two bigger sums for more established players than a number of players going for free after investing time and resources into them.
I agree with the sentiments regarding Gregor Rioch, it seems we've produced players just shy of the first team now for about 4 seasons or so, Burke being an obvious one, started brightly then faded off into loan deals before eventually being released. I hope that this trend stops with the likes of Weir and Gelhardt and that we catch the players in the Academy merry-go-round early enough for us to really develop them. I'd hope that the manager trusts in the young players, I haven't seen enough of that (maybe one or two making the bench, for example, certainly if relegation is avoided) yet, although Cook has signed good young players.
