The season kicks off next week. There's no way any of these guys have Time for Overeem.
ETA: Maybe he's taking tips on juicing without getting caught from a whole NFL team, that makes more sense.
Well its Fair to say that the Pro NFL team is getting training out of it also. Though i do believe "NFL Team" is an exaggeration and actually means 3-4 pro footballers (But i dont know). So the NFL players are doing something different to train for a day. Might be good for them since as you say it kicks off next week. And 1 day wont hurt anyone.
