I think a smart, attainable free agent could be JJ Redick. Imagine him starting at SG with Donovan at PG. And we could probably get him without sacrificing Favors. Korver has done well for us, but I believe that JJ is better pretty much across the board. He's averaging almost 18ppg this year. He isn't the type guy who can initiate offense, but he's a guy spreads the floor heavily for everybody else.
If we could put together an end of the game offensive lineup with Donovan, JJ, Korver, Joe and Gobert with Gobert setting screens, try to defend that...
