Just to reinforce what you're saying... There were at least six* cameras that could have had an angle on that play and we only got to see three of them. And one of the three was the initial live shot that wasn't zoomed in or slowed down. Very likely that one of the other three angles showed Brozio with his elbow clearly around the football before UIW 20 got it away.
*There was a camera on the SE corner concourse(1), in the east press box area at the 20(2), 50(3), and 20(4), a handheld camera on the field in the NE corner(5), and one in the north endzone pressbox(6). Camera 2 was used live, and cameras 3 and 6 were used for the ESPN replays. I'm guessing camera 1 or 4 was the one that showed the recovery.
