Who do you think will win the fight?
Adonis is taller, longer, and will fight til he's hamburger.
Derek A will sustain a broken nose or split forehead and call the fight.
If it ever were to happen...
I see it immediately going to a ground game, in which DA would try to outmuscle TA. After 20 seconds of grappling, a leaner TA would gain position and hold the advantageous position as they traded blows. Derek would tap out after the third face blow. TA could get hit forty times and he'd still be scrapping. He's got guts, I think the ELITE videos show fearlessness in the face of multiple beatdown threats. Plus the TA deadlift numbers show DA wouldn't outpower him by any means.
My money would be on TA in 90 seconds, with 3 of DA's fanboys making a ruckus at the match to make the riot the story, not the match itself.
