Tyrann Mathieu's personal foul on the 2 pt conversion

Cool tell us the rules oh wise one.
There's gamespeed, what the refs see and replay. It's easy to say what's right and wrong sitting watching in the stands or in front of a TV. The ball was thrown scrambling he got rid of the ball untouched you can't take more than two steps and hit any qb afterwards. It was a late hit simple.
