Whenever you believe it’d be best for Roy Jones to move up, vs prime Guillermo Jones. Who wins this matchup?
At the time when they both fought at cruiserweight, I would take Guillermo. Jones is obviously a far greater fighter but at 200 pounds, I will take Guillermo who beat the breaks off of Lebedev. Guillermo Jones was an odd fighter. He started as a massive welterweight. Too me, he was a better fighter as he moved up in weight.
The version of Jones you’d think is best suited to fight him, whether that be moving up just after he fought Griffin, or whether that be the version who fought Ruiz, or anywhere in between.
Sorry, I guess I should have payed closer attention to your original post instead of the thread title. Even though Jones isn't a natural cruiserweight, I would favor the 175 pound version that was at the top of his game circa 98' to 2001'. Too much speed and power for just about anyone.
