Gibson really seemed to have a decent grip on it and dude Peanut Punched it really really hard. I don't think there are too many RBs that could have held onto it.
I can agree that best case for Gibson is that his coaches see it that way. Appreciate your peanut punch source, which is a much clearer version of the play from same camera angle. Below I've added the url. Again, it's important to start/stop this play as often as you can through the moment Gibson's head snaps from the force of the punch. It's beyond any doubt, the brunt of this "punch" initially lands to the jaw & neck perhaps. From that point it's about the continuation of the fist, the angle to the ball & whether there's a direct hit to the ball. Another factor perhaps is what goes on with ball after it's out.
As before, I see the fist continuing across the tip or a piece of the ball. Is it what forces the ball out (?), I would say yes. But is it a clean hit & with a lot of force, enough to exonerate Gibson of fault? Not to me, I see the fist grazing over the ball more so than a direct hit. It can certainly be subjective, but what does a ball do that's been hit "really, really hard"? I've included the original source I had cited because we see the ball hit the ground and bounce up, maybe 5 or 6 inches. It does initially carom off the defender's knee, but I would hope to see more action from the ball than what you'd see if it had simply been dropped.
The original depiction that this was a "soft giveaway" I still see as being accurate. I'll note that both sources suggest a great play by the defender. What if Rivera and/or EB credit the defender? If they intend to go back to him then at some point they will express confidence, whether they actually mean it or not. Gibson's own explanation was this:
"I was super low to the ground and right before I got to the ground, he got it out" . Super low to the ground? Does that work for you, because it doesn't for me. Perhaps now they get away from running him up inside? He was more vocal this spring, that if he could go back he'd never agree with switching positions & that he wants more reps at WR.
