Simply put in my view, Hart at his salary >>>> Reyes long term at an exorbitant salary. In my opinion, you win with power. Take away Prince's 30-40 homers a year then dump Hart's 20-30. Assume that you use the freed up money to sign Reyes. That doesn't leave any money to sign a power bat. Even if the money was there, what free agent outfielder with power would come significantly cheaper than Hart? Look at what guys (Werth, etc.) have been getting on the open market. Hart for $9 million per is an absolute steal if you ask me. Do you trade Hart for an unproven guy to save some money? With Hart gone, besides Braun and Weeks, who on the 40 man roster as it's constructed would be able to be penciled in for 20+ homers? Frankly, who could you pencil in with confidence to hit even double digit homers? As far as I can tell, there are no true power bats in the minors. Gamel may be able to get you low 20's best case, but even that could be a pipe dream. Casey could bounce back with 15-20 again, but I'm not even sure that he will be around.
