NF: Tough Penalty enforcements

[Bob M.]

REPLY: To test their complete understanding of loose ball vs. running play, try this one.
PLAY: 2nd and 4 from midfield. A1's short pass to A2 is caught near the sideline at B's 45. B1 in attempting the tackle momentarily grasps (does not twist) A2's face mask. A2 breaks the tackle and makes a big looping circle back toward the other side of the field. He is hit at A's 47 and fumbles. The ball rolls to A's 45 where grounded B4 recovers.
