Lining up under center is hard for some quarterbacks. Taking shotgun snaps can be hard, too. It's even harder if you line up behind the wrong lineman.
Tyrod Taylor probably could have handled that snap pretty easily, but since he was a solid yard away from it that didn't happen. As a helpful trick, I try to look for who has the ball to figure out who to line up behind, but I'm not in the NFL so what do I know?
Fortunately Tyrod eventually figured out who his center was and the Bills would go on to score on the drive.
Monday afternoon, Rex Ryan trolled Taylor for the mishap:
Never change, Bills.
