I know Grey better than Grey knows Grey and Grey knows it.
No way in hell is he gonna tell you to drop Berkman for Loney. I doubt any of the other waiver wire options are ownable.
Your team is absolutely stacked in starting pitching. I wouldn't trade one of those guys for a Youk, who is injury prone and won't hit over 30 HR.
What I would try is an upgrade at 1B with one of those pitchers. Say, Berkman and Wainwright for Texieria (you might get the Tex owner to throw in a donkeycorn, too). He's gone through his April slump and his owner is probably pulling his hair out. Another guy to maybe aim for would be Adrian Gonzales with that type of two for one deal.

ETA-----> Morneau might be a good choice in a two for one deal, too. Grey has him valued about 20 spots higher than most places, he gets to go against the worst pitching division in baseball, it's hard to pitch around him with all the power batting behind him, and his home park is favorable.
See what Grey thinks.....
