On "The Drive", it is important to note that the penalty was "unnecessary roughness" when Dekkers was shoved down on the sideline. It was not called a "late hit."
So, Dekkers was being escorted out of bounds and giving ground, so actually the whistle technically should have blown even before the sideline, but it didn't. But there was no reason for a defender to shove the QB that hard when he was already headed out of bounds. THAT was the penalty. The TV analyst wrongly focused on whether the contact occurred in bounds. That is irrelevant. It was not a late hit. It was unnecessary roughness, which it truly was, unnecessary. The QB was conceding the play was over. There was no excuse for shoving him as hard as you can into the sideline area.
