I'm sure most people won't agree with me here, especially with the new emphasis on safety in football (which I think is a big issue), but I'll say it anyway: I think they need to relax the facemask rule. Unless a defensive player grabs and tugs on a player's facemask in order to make a tackle, I don't think it should be called. When Ra'shede had his facemask call on the Martinez sack, all he did was wrap up Martinez and his hand ended up on Martinez' facemask, which was most likely completely an accident. He didn't tug (at least from what I saw from the stands), and in no way did he use the facemask to make the tackle on Martinez that he otherwise wouldn't have been able to make.
Again, I didn't see the replay or anything on that play yet, but I've seen a lot of facemask calls in football recently that really don't have any potential to hurt the player player being tackled, and the tackle would have been made regardless.
