Devon Alexander to fight at 147?

If you have trouble making the weight, especially at a low weight like that, yes, it is better for him physically to move up. Boxers lose power when being drained, even a little. Alexander is a good boxer, but nothing more, I think. He could beat Mosley but because Mosley is not doing 100%. He won't beat Pac or Mayweather. I think his level at 147 would be a little less than Zab Judah's, after he gets used to the weight. I think that if Alexander tries to fight top tier fighters at 147, he won't win. Remember, styles makes fights, and he did have a good style against Urango. A rematch with Khan might be good, but won't happen, there are too many other fighters out there for Khan. I'd like to see Pac Man eat the ghost...
