Just want to get on record...You think that Stan Bowman is a Cup caliber GM? That if he took over any team that needed a total rebuild within about 3-5 years he would make them a Cup contender?
Either you believe that or you're playing Devil's advocate just to do so.
Honestly it's hard to say. The 2010-15 Blackhawks were built by 3 different GMs.
The responsible party for each:
Mike Smith:
Keith
Seabrook
Crawford
Tallon:
Kane
Toews
Hjalmarsson
Bolland
Sharp
Bowman:
Hossa
Saad
Niemi
And the rest of the finishing touches
The Saad-Toews-Hossa line was the best line in playoff hockey for 3 consecutive years and they don't win any cups without Toews and Hossa. Saad was the finishing touch that made the them an unstoppable force during the mid 2010s.
There were key pieces that contributed to all 3 cups that were acquired by all 3 guys as well, such as Bickell, Byfuglien, Frolik, Kruger and others.
Go look at the roster after capocalypse 2010 and it was pretty bare bones around the established core.
