The guys on the ends are members of the legendary Gracie Brazilian Jiu-Jitsu family. The man to the right Tim Tebow is UFC Heavyweight contender, Brendan Schaub. I’ve heard of plenty of NFL players training in various combat sports, but they were usually the guys battling it out in the trenches. Tebow is the first QB I’ve heard of to take part in MMA training. I have no idea how this will help with his funky throwing motion, but Tebow stands about 6’3” and weighs over 250lbs. I don’t doubt for a second that he can hold his own in the cage.
