Making the Conference Finals is a damn good season. Coming back from down 3-1 to be leading Game 7 with under 10 to go is a good effort. Not winning the Cup is not a failure - someone in the series had to lose. Obviously the competitive balance in the NHL has been a little skewed for a while - lots of writers/analysts (and fans) agreed that this series should have been the Cup final just in terms of intensity, competitive balance, and enjoyability. If you choose to see the Hawks losing as a sign of failure, that's really on you. I gotta hand it to 'fans' like you, though... who clearly either just became fans when they started winning, or are so blissfully ignorant of how bad the Hawks were just 7 years ago... making the playoffs once from 1998-2008.
Nazrark hit it on the head. If the Raptors (3rd place in the East) were in the West, they wouldn't even have made the playoffs. As for the Pats, outside of the AFC and NFC West, the AFC East (imo) was the best division.
