Great match up. I'm picking Julio, I agree his technique was too good and he wouldn't be bothered by Pryor's herky jerky style. Just re-watched the first few rounds of Arguello - Pryor 1, I don't see too much that would bother Chavez, if Pryor came out of his corner straight at Chavez I think he'd get dropped. Pryor takes the knockdown without being hurt and fights a more cautious fight, winning the next few rounds but takes enough body punches to slow him down later on, Julio comes on strong and wins a close decision.
