From The New York Times:
This fall, a number of former pro football players are trying to follow in (Lesnar's) footsteps. As part of the cast of Spike TV's reality show, The Ultimate Fighter, Marcus Jones, Matt Mitrione, Brendan Schaub and Wes Shivers will compete for a chance to fight in the U.F.C.
Mitrione, 31, said that intensity is part of what attracted him to the sport. A former Shotokan karate practitioner, he stopped training in martial arts in high school after he found success in football.
While the former N.F.L. players may not have made it in football, they are all explosive athletes, according to Rashad Evans, one of the coaches on the show, especially compared with the average heavyweight in mixed martial arts. And Lesnar's success, Evans said, has proved that power and athleticism can go a long way.
Yet technique is still vital in mixed martial arts, and unlike Lesnar, who was an N.C.A.A. wrestling champion, the former N.F.L. players are largely green. They may initially struggle because of their raw and and rudimentary skills.
