There certainly are pros and cons, as there have been peaks and valleys within the Sabres current developmental philosophy since Kevyn Adams took over as GM and Don Granato as head coach. Watching Quinn throughout the season, I think that he is on the verge of becoming a success story within that developmental philosophy.
I'm a firm believer that the Sabres made the right call in bringing him up to the NHL - and sticking with him - throughout the season. Sure, he could have had continued success at the AHL level, and there's something to be said for gaining that experience. If the Sabres were not in a rebuild and had a high performing forward group at the NHL level, my guess is Quinn would likely have been kept in Rochester to start this season. But, he would have had to face the AHL to NHL transition at some point. I'm pleased that the decision was made to do it this year. The confidence that I have seen growing in him and the improvement in quality of his play throughout this season has him poised to take a big step forward next season.
I can make make the same statement for Peterka. He just seems slightly behind the growth curve that Quinn has shown. Though as of late, JJ appears to have stepped it up.
