This is not my point of view. What I repeated many time is that I believe every team is providing good enough coaching for the players with the right stuff to make it. The vast majority of impact players in the NHL are there because of their talent and will to succeed. So in line with that, I think that the draft is by far the most important factor in finding future impact players at the NHL level. So it's not that I don't believe in coach/staff, I don't believe they make or break a player with enough talent, discipline and will. Many players that fail to make it don't even sign with the NHL team. The Hendriksson, Staum, Tyszka, Walford, Ikonen, Stapley, Houde, Gorniak, McShane, Olofsson, Leguerrier, Ruscheinski.
It's normal, and it's normal that among those that signs a contrat, many will not make it either just because they are not good enough to start with. No coaches would have made an impact NHL player out of the Bourque, Vejdemo, Bitten, Fleury, Brook, Hillis., Khisamutdinov. A guy like Fleury may end up a bottom pairing D in the NHL, Bitten or Vejdemo a fourth liner. They are late picks and have talent limitations that coaching cannot overcome. If Harvey-Pinard makes it as a third liner one day, coaching will havec little to do with that. It will be mostly out of will and hard work.
Also, in the past, we saw the Habs letting go young players that went on to have good careers in the NHL, the Robidas, Beauchemin, Hainsey, but none of the Leblanc or Tinordi and others were able to show Habs made a mistake with them by succeeding elsewhere. Again, most of the outcome is predetermined at the draft, either you pick a good one or not. That's it. That's why accumulating extra picks is so important. We have Roy and Farrell because of this strategy.
