Only Floyd's 1st Fights at a New Weight Give Him Trouble

In Floyd's career he has only really had trouble in his introduction to a new weight class. Castillo was Floyd's 1st fight at 135 (Castillo outmuscled him) Chop Chop Corley was his 1st fight at 140 (Chop hurt him for the 1st time in his career) Zab Judah was his 1st real fight at 147 (Sharmba was moving up to when Floyd fought him at 147) Oscar was Floyd's 1st fight at 154 (Floyd, and even Pacfarts should agree, is too small for this weight class) Its clear to me that adapting to the weight and dealing with bigger stronger fighters is the only reason he had trouble with these guys, once he got use to the weight (made adjustments) he steamrolled them. Pac on the other hand doesn't seem to need to adapt to bigger opponents or heavier weight classes, Floyd knowing his own struggles with moving up in weight is naturally suspicious of how Pac, an even smaller man than he is, has been stopping natural welters with ease.
