All fines go to charity too, so the players can write it off. These guys are just running their mouths, knowing that they can't pay but it makes them look like some kind of hero to fans who aren't aware of the rule.They can't pay the fine or any portion of it directly to the NFL since fines are deducted from the players game checks until it is paid off. all they can do is pay the player back of they really intended to follow through with their statements. (I highly doubt they will)
Also, if I'm not mistaken, if any other players or team officials try to compensate the player for a fine, they will be fined.
