I don't have any problem really with Pac taking on David Diaz first, just cause it would be his first fight at 135 and it wouldn't be bad to test out an easier fight first and see how he is at 135. Then a four belt unification fight.

And I definitely don't think Juan would be "picking on" Pac. Pac's turned into a big 130 pounder and would be by far the best fighter Juan's ever fought. I think its a tougher fight than Casa at this stage of Casa's career. Its easy to see why he would rather fight pac even if you think Casa's a tougher out which is questionable to me, its a bigger name, more money, and people who favored Casa would just say Casa's past it if he lost to Juan. Although I guess those who favored Pac would just say Juan's too big But we can see how Pac looks against David, he should win anyway but if he looks strong at 135 then a fight with Juan would be big.
