That bit was legal as all hell and the only reason he got a penalty was because backus was bleeding. He should have kept his head up. He is one of the biggest cheap shot artist in the league.
I'm not really a fan of either team but the principal point of contact was the head, that makes it illegal by the league's rulebook. If that wasn't the case Seabrook wouldn't have been suspended.
I think the St. Louis/Chicago is the most entertaining so far, should be another good game tonight.
