Like I told my friends last night about a hit from previous in the game, all of these now so-called "dirty" hits are just circumstance. You go to tackle a guy at the thigh and the ball carrier lowers his shoulder, boom, flag for helmet to helmet hit. A receiver jumps for a ball and you go to tackle him in the mid section and the combination of the receiver returning to earth and him curling up to cradle the ball and, boom, flag for hit on a defenseless receiver. What's a defender suppose to do? The Adams hit is somewhat in that category and it's being blown way out of proportion. Adams was falling toward Trevathan. When he lined up his tackle he was heading for the ribs but Adams was being tackled from the other side and therefore what started out as ribs ended up being facemask. His mouthguard flying out and all the Packers freaking out immediately just leads to an emotional reaction.
