Aside from the two point play controversy, I noticed many plays where the Lions player running with the ball and tackled in the field, had the ball spotted at least a yard from where it was when his knee went down. There was even a play near the end of the 4th quarter where the Lions RB got past the 10 yard line, setting up a first and goal, but the ball was at the 11! Maybe this is a one-yard Cowboys home game tax that opposing RBs and receivers are required to pay.
