Uhhhh...
Why would you ever let go of a players face-mask once you've grabbed it... even accidentally? It's 15 yards if you let go, and 15 yards if you go ahead and hold on to the darn thing and guarantee the tackle. The NFL really botched the rule change this time.
Also... the whole hitting the QB in the head rule is a J-O-K-E. It is an obvious way to let the refs determine the outcome of games (i.e. keep them interesting/ratings up) ... just like they use pass-interference. I love the Cowboys, that's the only reason I keep watching this WWF version of the NFL. I dare anyone to tell me that the Commish doesn't use his lackeys (the refs) to "guide" the season along...
I'll be happy if one person can show me a game in the last 3 years where the Cowboys had fewer bogus calls/non-calls than our opponent.
