The name is fine.
Changing it to some collegiate/minor league sounding name would be a mistake. Change for the sake of change is not always a good thing.
The Denver Nuggets have had a lot of looks, a lot of colors, and a lot of playoff failures...yet no one would ever be like "We need to change the team name because...well...just because....there's a minuscule chance that a new team name will mean more wins, yeah that's it". There's no reason to think changing it to Seawolves will result in a bunch of championships.
And the NHL doesn't need a Washington Wizards scenario where fans just think the new name is weak, the new name doesn't result in better play, and fans just clamor for throwback stuff anyway.
