Here is my question: why wasn't it ruled a fumble when it was stripped from him out on the field of play? At first I thought it was because a 2-point conversion couldn't be returned by the defense, but that rule changed this year, so tje defense can actually return a conversion attempt for 2 points of their own.
So, Roby picked the ball in the endzone, ran it down the field for a bit, had it stripped by the Pats while he was still on his feet, and it was then pounced on by the Pats. Why didn't it become theirs again, at that point?
