Both Rodgers and Quarless could have both made that play work.
1. If Quarless would have stepped up for the ball instead of letting it come to him he could have possibly caught it if not force the PI call.
2. If Rodgers throws it a bit higher so it doesn't hit the Redskins player in the back of the head.
It just didn't happen to go our way that time. Nothing wrong with the play call imo, we just shouldn't have waited until fourth down to call it.
