Ross by UD. Ross was the greater fighter of the two. They both are equal in height and reach, but I see Ross outworking him. Ortiz was tough as nails, but I wouldn't rule out a stoppage.
Do you have ANY idea whatsoever what you're talking about? How is a pure boxer who's only edge is in the jab category going to stop a stronger, more powerful opponent who holds the edge in in-fighting and was never even been close to being stopped until the very end of his career, having routinely faced bigger hitters than Ross, who wasn't even a puncher? Sorry, but I do believe you're talking directly out of your ass.
Ross UD. Ortiz is a bit underated at lw - IMO a Top5 - but Ross simply was a better and greate fighter. Ortiz was a bette infighter but Ross was no slouch himself and could hold his own there. Ortiz is the harder puncher but Barney´s chin was cast iron and he had a good defence. Ross has also the light edge in footwork and ring generalship and the much bette jab. I think he wins the fight on the outside and keep it there most of the time while holding his own on the inside. Close but clear UD for Barney.
Ortiz would win a very close decision..this is a dream matchup between two real masters...and believe me, no stoppage would occur..it would be a give and take strategic battle..a real connoisseur's fight.
