With Camacho holding on for dear life. The question though is will he win enough of the early rounds before Buchanan ups the ante in the last third of the fight? Camacho's foot and hand speed will cause Buchanan big problems here and Buchanan will have to turn it into a brawl on the inside becuase I don't think he'd outbox Camacho on the outside. Real close fight imo. I think over 12 rounds, I might edge towards Camacho, but over 15 I'd take Ken to edge ahead.
Buchanan by 15 round decision. Ken had more of an edge to him, and of course, he had more balls than Hector. His usual edge in skills would be diminished somewhat, but he would have nothing to fear from Camacho, and would outgut him for the win.
