Leave the first alone, veto the second.
In the first trade there is a lot of uncertainty, leave it up to those managers if they want to take a risk.
Blalock probably won't be too far behind Chavez
RJ is obviously the better pitcher but it might take him awhile to regain his form when he returns from surgery, meanwhile if Suppan pitches like he has been he could be very valuable.
I see Hunter and Lee pretty equal right now, Hunter will probably put up better stats at years end, but look how his second half numbers declined last year, he has a lot of work ahead of him.
I don't see very much risk in the second trade, I think its pretty obvious Pujols injury isn't affecting him very much, and even if it is just think how good he will play when he's 100% If I had Pujols I'd be hesitant to trade him for all three of the other players. That trade definetely gets vetoed.
