I'm sure he'd have better numbers on a better defensive team.
But the thing is this - even bad goalies on all-time bad teams can generally put up something in the .885-895 range. In Buffalo's entire decade of tank - and those were some terrible teams - they never had a team save % below .900.
To be at .874 means that you've been *really* bad or really unlucky, and probably both. You could drop the average ECHL goalie onto an NHL team and I'd expect better results than that.
This is obviously a flawed team, but if we had even OK-ish .900 goaltending we'd be right in the middle of the glut of teams from 5th-12th in the conference.
