There's not much to process. Every QB misses throws in every game every week. We over focus on it in Buffalo because our margin for error is close to zero. Most offenses you just move onto the next play and it's not an automatic drive killer.
Pittsburgh's offense has done nothing except when you handed them the ball in FG range. Kick this and play to win 13-10. That's unfortunately the game script here.
That wasn't a miracle play. It's a difficult NFL catch, the likes of which are made by every team every week. Of course here a pass hits the WR in the hands and you have fans questioning if it was off target.
