For just an exhibition game the Americans were taking a lot of unnecessary (?) extra shots, late hits, hits from behind, head shots. And the refs let most of it go unchecked. Don't think that will happen against other teams -- Canada has a reputation for dishing it out so it looked like they just let them play. Weber was fine; if anything, Kesler was lucky he got thrown out because Weber would have been coming after him. But Giroux wasn't very effective the rest of the way and I didn't even see Couture after the Oshie hit (I read that he returned in the 3rd but don't remember him doing anything). That was a bad hit, IMO. His head was already down so Oshie had to go way out of his way to deliver, essentially, an elbow to the head, from behind, driving him into the boards. With a linesman right there, watching it from 10 feet away. I'm not sure what linesmen are allowed to call but they really should expand it to player safety issues, if it's not already the case. Leave the technical stuff to the refs (what's holding, hooking, etc.) but heashots, hits from behind, boarding, hair pulling, head butting, charging, let the linesemen call those ones.
