Yeah I wasn't sold on him for years (mostly because I absolutely hated the PK until about a couple years ago, still don't love it but it's way better than it was) but you can't argue he gets results.So zero credit for developing them into #3s and Toews taking a jump and Makar being arguably the best player in the league and the countless scrubs turned into NHLers. People just want to focus on the negatives without acknowledging that the Avs have arguably been the best team in the league at developing defensemen since he came aboard... and before that his years in the Columbus system brought along a lot of really good defensemen as well.
Pratt is an elite coach of defensemen. The track record is as good as anybody in the league today. He gets players to be elite, he gets the best out of middle talent, and he can rounds scrubs out into NHLers.
Avs have been an elite defensive team and I believe one of the best teams in the NHL at preventing rush chances for quite some time now. Don't think you can ask for more than that from your defensive coach.
