Getting out worked and out hustled by a D2 team.
I hate to be "that fan" who overreacts but it could get extremely ugly this year. It's one thing to not have a ton of talent, it is another when the guys can't do the fundamentals, don't hustle after loose balls, getting out rebounded by much smaller teams, etc.
Hopefully it is just a case of a lot of new players and a new coach, and they just need time to get it figured out.
On another note, I said it yesterday but how awesome would it have been to have Mathieu on last year's team?
