I'm wondering if anyone else saw this and knows what was going on. Watching on TV after the Broncos came out on the field, before the delayed kick-off, the cameras went to the corridor to the Ravens locker room. They had a few officials standing around as the Ravens began pouring out into the hallway and on to the field. I noticed several BIG linemen going through a quick turn-around pat down by an official. It didn't seem to be random at all, as most of the guys were leaving stage left, several just walked forward, stopped and spun a 360 while a ref did a quick frisk (real quick, patting the pads type of thing).

Anyone else see this? Is it common??
