Unless his staff is absolutely loaded, it's going to be hard to get both those guys for just Pujols. I disagree that McGriff will fill the Pujols void. Two suggestions:
You have several pitchers that might post similar numbers in the 2nd half. You might get both guys by giving him his choice:
Pujols + (either Wells, Padilla, Lilly, or Ohka) for Clement + Hudson
Or, you could try and deal Pujols + CrimeDog + his choice for a real good bat and one of those starters you need.
