Funny, because I thought the majority of the holding came from the Gophers and was not called. The calls made against Clarkson I really have no complaint about, except the body checking call on Rattray, which was bogus. I really didn't see much obstruction or hooking from either team. I thought the officiating was Minnesota biased and the line work was horrible for both teams.
As far as who had the better of play, I'd say it was a toss-up. Minnesota clearly controlled the first period. I thought the second was pretty even with each team doing what it does well. Clarkson was tenacious on the forecheck and Minnesota was great at creating chances with skill plays. The third period, I thought, leaned more toward Clarkson, mainly because, as you mentioned, Minnesota made mistakes. I would say that the mistakes were due, in part, to Clarkson's pressure.
