OK lets see:

ODH, old and weight drained.

Hatton, already KO'd by Floyd.

Cotto, beat to death over a long fight with Margarito. What was left of Cotto was no match for Pacquiao. Impressive win a year ago? Yes. Impressive win after Margarito? No.

Clotto, lost to Cotto.

What more needs to be said? Pac is nothing until he beats Floyd.
