I just looked at the thread about him vs. Diaz, and I think he could go even further than 135. H'd beat the ****ing **** out of Gavin Rees and probably stop him within 6 rounds. Could he beat Malignagi too? Probably not, but I wouldn't bet against it. Malignaggi is perfect for Pac, but has a lot of physical advantages on him. Could he go further? Almost impossible, I think, but if he did, his legacy would be set. I think he could collect a belt at 135 and 140lbs.
I dont think so, A lot of guys that fight @ 140..or so...are guys that are naturally 150 or higher. The size difference would be huge...Pac's power wouldnt have the same effect.
At 135, against David Diaz, he has a good chance. Against all others, he would be hard pressed. Heck, he has not even dominated 130 yet.
PAC may easily go up to light middleweight and win following titles. 135 - WBC David Diaz 140 - WBA Gavin Rees, 27(13)-0-0, height 5′ 3″ 147 - NO 154 - WBC Mayweather
135 yes, 140 no. Those guys at Super Lightweight are too big for Pac, in terms of height and size. He will get killed for sure (from 106-140? lol)
