[over the mountain]

can someone explain to me the guys who stand on the sidelines with the striped yellow (and another color) type of shirts on. im guessin they are either ball boys or the chain gang or the down marker guys. what i dont understand is why one of them was emphatically celebrating when gano missed the late field goal in regulation against the titans in tenn. i mean fist pumping you thought he was a coach celebrating gano's miss.

please do not tell me that the chain gang guys are locals to whomever the home team is. down marker guys i dont care, ball boys i care alil bit but chain guys . . .dont trust that, not by the way this guy was clearly biased.

saw this on a video on nfl.com
