If you've got 6 minutes, watch this video. NFL films routinely wires up players for audio - typically to include snippets of hits or sideline banter in end-of-season highlight reels.
But what happened during the Lions/Browns game two weekends ago was remarkable - and listening to the audio from rookie QB Matt Stafford as he commands a comeback (starting down 21 points) is phenomenal.
Then he gets flattened, as time expires. And, well... just watch it. Really incredible.
