Come on... Were you watching during those years? It was clear he didn't have the fire and it reflected in the team's not caring play so much of the time. Recruiting on the D end also got to a bad place at the end.
2008-09 - 2010-11: The teams sucked
2011-12: Great, overachieving year
2012-13: Disappointed based on expectations
2013-14: Great, overachieving year
2014-15: Disappointed based on expectations
Every year after that they were not great
All those Big Ten championships at the start of the conference? The conference was brutal during those years. Then Notre Dame joined and immediately jumped near the top, which says a lot.
This is what I don't get. What are the expectations. National Championship every year? Tell me who has done that. He is one of two men ever, to lead Minnesota to a title. One of two, but he's always put down.
2008-09 - 2010-11: down years as he's fighting an illness. Maybe some know how bad it was, but I don't. I think we can extend a little grace here. Plus he led the team back out of those days. He was allowed to work though the rough years and led the team back to national prominence. he doesn't get nearly enough credit for that.
2012-13: They lost in OT to the National Champion. Yale beat UND on the next round by multiple goals and I think won the title by shutout. I suppose it would be better if they lost in the championship, but you play teams when you play them, and they gave them arguably their best game.
2014-15 (and beyond): Back to that expectation thing. If being the best team in your conference and among the best in the country doesn't qualify as success, then what does? What else do we hold to that standard?
The guy was one of the best in the country at his job for over 15 years, and led Gopher hockey to more wins than anyone else, 5 frozen fours while while played in a far more expanded tournament than his predecessors, and recruited players when they had more options than ever. He had to fight against more opponents in College hockey and against NHL $$ in the kids' sights.
I'm sorry I don't mean to be the Don Lucia apologist, but it's always bothered me the bad rap he seems to have to carry around. It's seems fans want to wash away all the good, and nitpick the little bit of bad. I've never understood it.
