It amazes me it has taken this long to crack down on this. This has been going on for years and they just now address it? Maybe I'm just a traditionalist, but play the game, be a man, and leave that crap out of it.
I guess I'm in the minority judging by some of the comments here, and apparently many of you wouldn't have a problem with a group of kindergarteners flashing a gang sign because they saw their favorite player/role model do so on national TV.
As far as a sign having a different meaning...it's pretty darn simple. You tell the players 'Do these signs, get fined. You want to say hello to your peeps back home, come up with another way...in fact...we're pretty sure you can all afford cellphones to go with those inexpensive vehicles you're driving around nowadays. You're here to play football...leave it at that."
