Players are not involved, not told to lose, no way. If there was ONE SHRED of evidence and / or if ONE player comes out to say they were told to lose, all hell would break out in the NFL.
Maybe a coach will be told to find a way to call some bad plays or bad defensive formations or put in the wrong personnel if the game is close... or maybe he will do it on his own to get a player like Young instead of the #3 pick.
