Haren's a better buy than Greinke at this point. Get Haren.
Hamilton's going to age terribly. In a couple years he'll be putrid. No discipline, no eye. Avoid like the plague.
Sign Haren and a left fielder. Trade Morse for a reliever, extend LaRoche at 1B.
I'd still go after Bourn and figure out who will play LF. If you can have Bourn and Werth at the top of your lineup, that's nearly 10 pitches to start the game every single time and that's before you get to Zim and Haper and LaRoche or whomever they chose to go with.
