What will i have to trade to get these players???

Not to sound like I'm bagging on your team, but you have to do something. Your outfield is pretty weak and your pitching is atrocious for a fantasy roster. You're making the right decision to try to get two legitimate aces that you'll be able to count on down the stretch, but you just don't have that much talent to trade. The only position players with any value in a trade are ryan howard (that's a given), mark reynolds (shop him now before his value plummets), and david ortiz. You need to trade all three of those guys to get the aces, but you can probably bolster your roster with a 1b to fill the vacancy or you can try to improve the outfield. Since you have so few good pitchers, try to bolster your staff with 1 and 2 inning guys that get a lot of K's like broxton, qualls, okajima, etc.
