re: Worst call I’ve ever seen in HS, college, or pro.

No doubt that was the worst. I was at that game. DB made a great play and intercepted the ball and the official (his name was D*ck Pace) threw the flag. We thought it was offensive pass interference as the receiver definitely made early contact on him.
That Egg Bowl was handed to Mississippi on a silver platter.
Ugggghhhhh

This call here. Not sure it is the worst call ever. Possession was certainly in question. As a receiver you have maintain possession all the way through the play and he did not.
Tough call by the ref but not necessarily a bad one.
