The NFL supposedly does all it can to protect the players.Ok Bell scores but because the helmet came off the score is taken away.That did nothing to protect either player,and in fact,it ended up getting more players injured.They really need to rethink stopping the play where a players helmet comes off.Why penalize a player by taking a score away when he did everything he could to score,and got knocked out in the process.I could see it if a player without a helmet attempts to get up and continue the play,but when he is down for the count,that's just stupid.
