Cannot tell from these selective pictures/video what Jennings left leg does. Inconclusive at best...which is why the NFL said there wasn’t enough evidence. They did not confirm the call.
I have no dog in this fight (college football fan) but that call appeared to me to be totally blown by the rule of simultaneous possession that I heard.
The biggest problem is the officials losing control of these games. 24 penalties in both of the Sunday night and Monday night games. This will get worse now.
