Explanation on NFL Network

So, apparently, when the QB gets flushed out of the pocket, like Dak did, then DB's are taught to jam the receivers at that point. Apparently that's legal as long as the ball isn't in the air. I guess, because, at that point it's sort of a quasi run play--again, as long as the ball isn't in the air.

Talib apparently jammed too late.

I forgive him. He's been solid otherwise. He's allowed a mistake on the year.
