If you’ve ever wondered how football players aren’t sometimes eligible for Academy awards, then you’ve probably witnessed a play that’s been reversed due to trapping. When a quarterback is under pressure from the pass rusher, he’ll do his best to  get the pass off before he’s hit, which can result in a pass that’s got a lower trajectory than it should. When a receiver dives for the ball, his hands and/or arms must be between the ball and the ground for it to be considered a complete pass. If not, the play is ruled incomplete due to trapping. Most receivers try their best to convince the refs that they completed the pass, and if it wasn’t for instant replay, a lot more of them would probably get away with it. Even with it, camera angles don’t always allow for conclusive evidence of trapping, so sometimes the call comes down to a player’s acting skills.
