re: How did the Indy Punt returner have possession but Dez Bryant didn't?

As far as what constitutes possession, yes. Cribs possessed it, was hit, hit the ground, then the ball came out. Down by contact, Indy ball. It's incredibly simple to see.

I mean different as in he didn't have to take two steps are make a football move. He just needed control of the ball when he was hit. Which he had.
