My thought is WHY IN THE WORLD WOULD ANYONE HAVE TONY TUBBS IN A FANTASY MATCH? YOU CAN MAKE ANY! WHY CHOOSE TO WATCH PAINT DRY?
Tony Tubbs in shape and motivated 229 Lbs. Easily decisioned Page. Tony Tubbs in shape and motivated barely lost to fast rising Riddick Bowe. Tony Tubbs in shape and motivated UD Bruce Seldon. Tony Tubbs in shape and motivated UD Orlin Norris (but failed the drug test and changed to No decision). Even grossly out of shape at 244 lbs, Tubbs went 15 rnds with Witherspoon, losing a fairly close decision. Tubbs at his best was like a Jimmy Young with better movement but not as good chin. It's possible that Coetzee lands a Bionic Right and gets Tubbs out of there, but if Tubbs is fit and motivated it is more likely Tubbs uses his excellent jab, quick hands and feet to win a UD.
Tubbs would do great for the first five rounds, might even win all of them. After that Coetzee starts catching up to him. By the 8th Tubbs goes down, gets up and takes some shattering right hands before the ref stops it.
