You’ve got to remember though, Tito taught us about the concepts of the young-old and the old-young. What if it turns out that Marvin is an old-young?Contrary to the posts, I think Marvin would beat Cannonier.
I'd say he would probably be the favorite over most MW's. He's got an insane chin, great pace/cardio, good striking, good grappling, good size, good reach. What's crazy is that he is still so young.
