Well, let's put this into perspective, the Hawks went:
2012/13 - Cup
2013/14 - WCF game 7 OT vs. LA (Cup champs)
2014/15 - Cup
So really, they were one single goal away from making it to the finals in 2013/14 which was a year everybody thought the Western Conference was winning regardless. So to say they were hypothetically 1 goal away from winning three Cups in a row, is that really THAT much different than if Pitt wins three in a row? They were competitive all 3 years.
Sure if one wants to talk about hypotheticals. We'll find out in a couple of months if PIT can actually win 3 in a row. But then they've already done what Chicago couldn't - win back to back. So maybe start there before talking about they were "hypothetically" 1 goal away from winning 3 in a row.
