I was at the game last night, and I don't really know if I saw dirtiness from the Devils, but they were hitting a lot more than I'm used to seeing and there was definitely an edge to their game. I didn't see a lot, or any, late hits or stuff behind the play. There was one incident with Severson chopping at Kreider, I believe it was, and Tootoo trying to mix it up with Hunwick, but it all seemed like regular hockey related stuff and not goonitry.
Then again, my perception may be very questionable since it could be homervision. I didn't see the Larsson elbow since it was against the boards I was at, so I got nothing about that. Seems very out of character for him, though, so I wouldn't read a whole lot into it.
Also, the booing incident seemed like mostly Ranger fans, since there were a lot of them left, especially in the lower sections, but I wouldn't blame any Devils fan for booing them after that Merrill giveaway. I dunno, I think it's rather classless to boo the home team during the last home game stuff at the end, especially if you're a fan of the visiting team. Whatever, raggys should enjoy the superiority while it lasts because it won't be around too long.
