Hello Everybody,
I'm going to divide the Sabres history into thirds in order to give an impartial comparison of different eras:
From 1970/71-1987/88 the Sabres win percentage was 54% and they made the playoffs 13 times, going past the 1st round in 7 seasons
From 1988/89-2005/06 the Sabres win percentage was 46% making the playoffs 11 times, advancing past the 1st round 6 times
From 2006/07-present their win percentage is 44%, making the playoffs 3 times, advancing past the 1st round once
If we further divide the present era into sectors, before Pegula, from 2006/07 to 2010/11, the Sabres win percentage was 55%. From Pegula's first complete season as the owner, 2011/12 to present, the Sabres win percentage is 36% and they've made the playoffs zero times. The reason I am not including the 2010/11 season in Pegula's record is because he officially took ownership on February 18th, 2011, 68% of the season already completed, and the only subsequent moves that season were trading a second round pick for Brad Boyes, and waiving Craig Rivet. It's worth noting that the Sabres did make the playoff that transitional season, but lost to the Flyers in the first round.
During that same span that Pegula has controlled the Sabres:
The Boston Bruins have won 64%
The Maple Leafs have won 52%
The Senators have won 45%
The Arizona Coyotes have won 40%
The Buffalo Sabres have won 36%
Hopefully, the above math will help to put things into perspective. I can't vouch for it's 100% accuracy. It's pretty close to the truth, but feel free to make you own calculations.
