Tua certainly had his vulnerabilities, but I wouldn't make either of these fighters a reliable favorite to beat him over the course of an entire fight.
I think if Tyson can't KO one, and required a twenty something punch combination to KO the other, I think it's pretty easy to assume that Tua wouldn't get a KO. I think Pinky keeps his jab in Tua's face and Tucker out-boxes him.
Thomas was typical of the '80s HWs - he had one or two standout attributes that he parlayed into a couple of big wins, but he wasn't well-rounded or consistent enough to have any sustained success. The '80s HW division always felt to me like it was populated with "good journeymen" fighters (excluding Tyson and Holmes, obviously) - the kind of fighters who could pull off a big win or two under the right circumstances, but otherwise lose most of their big fights and never entertain any serious discussion of being great.
