I'm done with the NFL

by definition, that means it wasn't a penalty...look up pass interference...the rule states it has to be a catchable ball.....

Also, not sure he touched him, he certainly didn't push him as some commentator said.

I know the rule. The officials know the rule. It's also a judgement call, and the guys on the field had a different opinion than mine.

It looked to me like Robertson pushed him, and at a minimum, he extended his arms, IIRC.
