Do people need to be constantly reminded of Pac's performances against Marquez?! Marquez is the best fighter Pac has faced...period. Some may argue that Pac wasn't as "complete" a fighter in their first fight...fine. But he clearly was by their second fight...and Marquez showed that a skilled counter puncher will give Pac fits. Well...Floyd is faster and just plain overall more skilled than Marquez. Has anyone seen Pac have a Plan B in any of his fights? He fights one way...overwhelming his opponents with his pressure and stamina. But if you cannot adapt against someone like Floyd...you will get picked off all night. Lets not forget that Floyd thrives in the gym. The guy has incredible stamina. He isn't Oscar, Cotto, or Hatton. If he needs to dance all night...he will dance. If he needs to counter...he will counter. If he needs to be more offensive...he will be (as he showed against Mosley). And he can do all 3 things in the same fight. He has a plan A, B, and C. Pac will be a tremendous challenge for Floyd...simply because Floyd has never faced a GREAT PRIME fighter with so much momentum. But Pac has never faced a fighter has smart, fast, and skilled as Floyd.
