Common belief, but you aren't going to teach defense like Korczak plays. It isn't just his absolutely mistake free game, but he just doesn't make bad decisions with the puck either. I have talked to several scouts, and they all think the same - Korczak has the potential to be an absolutely elite defensive defenseman. That is not to say he has no offensive game to speak of, but he doesn't take risks. He doesn't make mistakes, and he is just as solid as they come as far as junior defensemen go. This is the kind of defender that Team Canada always looks for. A Vlasic type, who just refuses to give up his defensive positioning for offense, and when the puck is on his stick, he makes the smart play, not the risky play. He moves the puck forward in a positive manner and rarely gets caught on the wrong side of the puck. Thomson is certainly more flashy, but I don't know that his offensive game is good enough to make up for all of the risks, mistakes and turnovers he makes.
