last part possibly true (impossible to know the unknown), first part no way, wrong, watch it again.
He and Fredrick look at each other and neither lays out to stop the receiver. The other one they'd likely score anyway, but if he laid out to stop him right before the goal line who knows what would happen, like with the game ending play you never know.
As already said it's Impossible to know the unknown but like with Jim Brown lamenting our RB's going out of bounds instead of taking a hit getting an extra yard or two a few years back, the defensive player in me has noticed it's not just our guys, very few give the extra effort and lay their bodies out to stop a guy whose ahead of them.
