I think the recent Blackhawks teams that won the Cup 3 times had the best overall roster.
Toews at his best was being compared to Crosby - Selke & Conn Smythe winner.
Kane - Art Ross, Hart, and Conn Smythe
Keith - 2 Norris & 1 Conn Smythe
A big difference between the above and the TBL stars is that these guys didn't just contend for the top awards, they actually won them. Hedman is the only TBL guy on the current squad who is at award level with his Norris last season. Stamkos' Rocket years are a thing of the past.
Then, the Blackhawks had a wicked and extremely deep supporting cast with the likes of Seabrook (forming the best pairing in recent history), Hossa, Bolland, Bickell, Byfuglien, Madden, Hjalmarsson, Ladd, Sharp, and Versteeg. Other good players came and went in this era.
It's really no surprise that they won 3 Cups. It was a marvelously built team.
