Go Texans!
My interpretation is that Jones dropped the ball on his own, but even if he would've grasped it, KJ would've pulled his hands apart and dislodged the ball.
I wish you could see the zoomed-in version. You'd see Kareem's hand so loosely cupped it looks like he's doing it just for the sake of getting some balance and sticking closer to Jones.
You know when a receiver places a hand on the top of the defender's shoulder pad to steady himself to make the jump up toward the ball? To steady himself, plain and simple. If anything, KJ is just trying to hang there in the pocket with Jones. I'm telling you guys, KJ wasn't ripping the guy's arm. The ball Kah-Pings! right off Jones' hands and then you see Jones still trying to use his hands to follow the ball downward and track it down to catch it...but it ricocheted so quickly that he had no chance at getting it. It was the very definition of stone hands.
In fact, michaelm, the replay will show that KJ's "iron-grip hand" comes off of Jones' bicep so easily and so quickly, that I don't even think KJ was pulling all that hard if any at all. There was no follow-through when KJ's hand detaches from Jones' bicep.
It's plausible that KJ wasn't tugging very hard, in my estimation at least, because he didn't want to get flagged for interference. That's a micro-second of time that he has to to decide if he makes the tug or doesn't...and perhaps HAD he tugged too hard, the ref flags him and the Falcons get the ball 1st and goal at the 1. So, all in all it's good that it worked out like it did.
