just to name a few on here....every league has their guy who never turns out, it is about recognizing them early, if someone is at a bantam game with lawrenece playing i personally would like to know "hey this kid is suppose to be good lets see what he is like" then if he turns out you can say "hey I saw him in bantam" if not then just rack it up to another player that never turned out. In the end most players do not turn out because of something they do wrong such as Steve Anthony (attitude he thought he was better than everyone else, his compete level as pretty bad and lost some serious years in training hard), Patrice Cormier (his hockey sense in higher levels was evident when he made higher leagues and caused him to not turn out), Nathan Noel (size for style of game is his downfall), Luc Deschene has 0 compete level and 0 training hard off the ice, kind of lazy on the ice, skill level up the yang...anything can happen but right now as of this clip in time this kid looks like he has something.

then you have the other end of the spectrum such as Claude Giroux passed over in two straight OHL drafts to come to Gatineau to be a 1st round NHL pick and NHL superstar (how does that happen), Paul Byron passed over by OHL teams to come to QMJHL.
Nothing is perfect when dealing with young players, never will be, just have to make the best guess
