Solid fighter, not in the skill league of a Page or Tubbs, but real close. Chin really hurt him, otherwise would've done better.
Overall, or based on pure potential? I'd forgotten to put Greg Page on my initial list (as stated earlier) so he'd probably be fifth on that list knocking Dokes just off it, Tubbs would be after that. Ability-wise Page was amongst the top 3 of these fighters IMO.
I don't know if Dokes' accomplishments really warrant his being rated above those guys. Sure, he got a win over Weaver, but that was one of the worst stoppages of all time, and the rematch resulted in a draw that many felt hercules had one. Additionally, Weaver had wins over Tate, Tillis, Coetzie, Williams, and Duplooy. Dokes had close decisions over Cobb, Rodriguez and an old Young. Not particularly impressive. Berbick was probably deserving of being rated above both men. Thorughout the course of his career, he defeated prime versions of Tate, Page, Thomas, Green, Bey, and canadian champion Racette. That's a decent list. When we consider that Pinklon Thomas was undefeated and viewed by some as the best heavyweight around in 1986, this was a huge win, likely better than any Dokes ever had.
Very well put. My take on Carl Williams is that he was an extraordinarily well coordinated athlete with limited durability and intelligence. He did appear to wilt a bit from the late round body attack Holmes subjected him to, and others have pointed out his deficient chin and vulnerability to the hook. His lack of a true killer instinct cost him dearly against Weaver, as he failed to distinguish between serious distress and what was possibly a ruse on Mike's part. (Hercules was clearly in nothing like the kind of trouble Bonecrusher immediately had him in the next time Weaver stepped in the ring.) The Truth wasn't really an underachiever as I see it. Carl did very well considering his limitations. But if he had managed to upset Holmes, he would have been little more than a transitional champion. He was never a candidate for ATG status, even if his execution was completely mistake free. What he did was perfectly satisfactory, compared to all the others of his era who should have done so much more.
