People downplaying the penalty are being dumb. You assume that he could have just grabbed it, but if that was the case why didn't he do it? What if he tried to grab it but in his excitement bumbled it and a Lions player was able to get there in time and recover it? Was it going to go out on it's own anyway? Possibly, but you don't know for sure. You can't simply dismiss the penalty because X, Y, or Z was going to happen anyway. None of those other things happened, but you know what did happen? Him knocking the ball out of bounds illegally. It was an absolute missed call, and the Seahawks once again got lucky.
