Im not sure Roy could beat him Roy's good but at some point its a blown up MW against more than he can hande Duffee's speed, movement and power is better.
Someone said Pat Barry today and that is the one that makes the most sense. Duffee vs Barry And Roy would KO him.
They need to move duffee up slow he hasn't even done anything since 2010.Not super slow but he doesn't need to be fighting roy nelson next that's just stupid.
Roy's not at the stage where he needs to be fed anyone. Duffy hasn't earned it and Roy would make BBQ sauce with his blood.
Speed and movement, yes; power, no. Roy has some of the best one-punch power of any HW, and that includes the likes of JDS, Carwin, Overeem, Hunt, etc. However, I do think Roy will eventually lose to a fighter like Schaub/Herman/Mitrione/Duffee. All of those guys are faster, more mobile and have a longer reach. It's just that they keep getting lulled into brawls, and Roy is so dangerous early in the fight. (Notice how almost all his wins come in the 1st round). One of these days, a mid or even lower-tier HW will fight smart and "elusive" and get a UD on Roy. They just need to stick-and-move, circle away from Roy's right and land enough jabs and leg kicks. They may hear boos from the crowd and get called names on Sherdog ("too elusive!" "that boring Condit-Diaz gameplan!", but it will work. With that said, I wouldn't pick Duffee...yet. I need to see more evidence that he's improving and has a decent fight IQ.
