Frightening to give up Wainwright, but Dempster can solidfy the middle of your rotation while Lee is out. You'll have Sabathia, Lee, Dempster, Kuroda, and Anderson that is very good there. You can always matchup the back end of your starters with weekly 2SP or daily matchups.
Lind is the most valuable piece in this deal by a hair over Wainwright.
Tell you the truth though, McCutchen is no slouch himself. I can see him being the next Carl Crawford. I think I'll pas on this simply because in my book there isn't a huge dropoff on McCutchen and Lind.
The best there is, the best there was, and the best there ever will be!
