Im surprised no one is mentioning the challenge that CJ made to Roy and how Roy didn't seem to take it too kindly. He was really trying to lay the wood out there on everyone. He leveled Chambers, too. You could tell he took CJ's challenge seriously and wasn't going to play around with any WR.
Didn't you know? All professional athletes are granted the ability to stop all motion at any time. I guess he wasn't paying attention or something, and forgot to hit the "freeze time" switch.
