I thought that throughout the game they were letting them play. Tons of calls that have become 'run-of-the-mill' penalties like defensive holding, PI, and late hits on the QB were totally ignored. It was like watching a game from the 90s.
Now, I am all for those types of rules. I hate the way they enforce them these days. BUT - you can't call every little thing all season long then 'let them play' in the Superbowl. Thats BS and I thought it was a horribly called game overall, when you consider how tight they have called games all season long.
Taking that into account, I am suprised there wasn't 3 flags on the ground after that contact.
