Coleman...and it wouldn't be close unless Royce can knock him out really quick with a shot to the jaw. Bigger, stronger guy usually wins in a street fight. Here, you are looking at a 130+ pound weight advantage....Royce gets killed here.
Royce by choke, arm bar, leg bar, neck crank, americana, leg triangle, arm triangle, wrist lock, or just tie him up until he has a heart attack from exhaustion. I love Ronnie but you're talking about a fighter against a bodybuilder.
I don't know who would win, but here is gracie defeating some big guy.
that guys is a washed up sumopathetic muscle and strength levels compared to ronnie in his primeall that fat weight also takes a bigger toll on the heart than muscle mass plus ronnie is a black guy on large amounts of roids, so his level of agression would surpass that of a pitbull in a fight
"never tested positive for steroids"
Ronnie would have to get hold of Royce quickly before his stamina run out. Ronnie would be winded after only about 2 minutes so depends if he could punch, kick , arm lock or strangle Royce in that first 2 minutes. If he was able to do this then Ronnie would have a real chance.
