One of Lesnar's old MMA coaches claimed that his measurables(40 time, bench press, vertical jump)were equal to or better than Mario Williams but he was so raw when it came to understanding how to play football that the Vikings wound up not signing him?
I would say T.O. in either boxing or MMA...great size, great athleticism, grew up rough, mean streak, put the beats on a much larger Hugh Douglas

, and was never someone who totally could make the team concept work....he needed to be an athlete that only had to rely on himself...then he could've been champion.
And you know he could've sold the hell out of a fight w/ his sh!t-talking
