I think it's fair to say that both games last night were somewhat surprising. Norwich was the favorite despite Williams having a solid season, and no one thought Endicott would keep the game that close against Plattsburgh.
It will be interesting to see if Plattsburgh can re-focus and collect themselves.
As for Norwich, I wonder if some of the mystique has broken away this season. A few teams have played them very well and even tied them when they weren't supposed to. I know Castleton (despite the final score) walked into their game last weekend feeling like they had a chance (especially after the 3-3 tie earlier in the season), that's not something that has happened very often in the past. Plymouth also played them tough this year.
Once the mystique is gone you lose part of your edge. They're still a great team, but I wonder if the door has opened, even just a crack, for other teams.
