Coach should have called a time out and let them see the replays. Either off side or poss PI on Norman. Then a botched punt. Now Washington has great field position.
This was a topic on local talk radio in Indy about bad tackling in the NFL. One of the guys opine that too many of the smaller guys go high and try to wrestle the runner down. Go low and wrap up the legs. It hurts but it is effective. I remember that pain from when I played in my youth.
