I disagree. A block is to the torso, not above the shoulders and no where near the ball. That douche was so proud of himself for laying Lockett out, he was cheering and patting himself on the back. After, he was scared, thinking he was going to get his ass kicked. In the old days he would be in the hospital too, but the Seahawks showed restraint and didn't target him.
If I was the Dallas coach I would have benched the douche in respect for Lockett. I'm sure he will be fined.
