I can't think of any goalies outside of Khudobin's hot start this year that really succeeded after their time here, least as long as I've been a fan (2009 Leighton onward).
Mo and Lavi were who we thought they were. Mo can get the most out of a veteran group of guys, which is why, at long last, he's taking a decent Jets team to success ('cause they finally got goatlending). Lavi can get the most out of a team for 3-4 years, then they turn on him. Muller sucked, Peters....I like Peters, I think he'll get another job if he's canned here.
