If you are intent on trading those three pitchers (which is a pretty good idea considering a lot of teams are short if you have that many), I would try to trade Lowe for someone like Kent. They went within two picks of each other in my draft. Millwood or Colon for a solid first or third baseman. You could package your existing position for a good trade(like Colon and Olerud for Sweeney or Millwood and Coskie for Glaus or Chavez). I would only use one pitcher for first or third and leave the other position pat. Your third trade, I think, should be a package deal for an OF and a RP. How about something like Millwod for Damon, Urbina. You'll have to tweak that one to make it even enough for someone to take a trade, but I think you need to address those two positions. If you are certain about booting saves, you could try packaging your remaining corner infielder -- something like Millwood, Coskie for P. Wilson, Hinske. Whatever you do, I would recomment getting at least one OF in the trades (I have your OFs at #35, 41, and 46 respectively on my list). Long message, hope it helped. Please see mine if you get the chance.
It's time to roll the dice.
