I thought chop blocks were illegal already. From my understanding a chop block is diving low on a player that is already engaged with another player. That was already banned. So what are they banning now? *tried to find an explanation but didn't come up with much besides "chop blocks could still be used during certain situations" the last few years. Knowing the stupid NFL rules it is probably something like "Chop blocks are permitted by a team who's sock color had changed from their previous games. Color combinations worn during consecutive games eliminate a teams players from chop blocking opposing teams linemen. Also, the left sock must remain in a fixed position at all times. Any player caught adjusting the left sock will be fined and a penalty will be enforced upon kickoff during the second half. If the penalty occurs during the second half of the game, the players team forfeits their rights to any Gatorade purchased by The National Football League also the next offensive possession the first catch will be ruled an incompletion because we have no idea what a catch is or isn't."
