These guys hear cheering each week and they know what's what.
When even the defensive player that knocked him out says that, I think there's something there.
Was it everybody? No.
Were there fans doing it? Absolutely. Watch the tape, listen to the cheering, it usually stops when a player is down on the field being attended to.
Good for Eric Winston taking center stage on this one.
Way to stay classy, Arrowhead Stadium.
