I'm gona assume that your util- is Carlos Lee. You have a pretty good team. Your offense is solid up and down the line, If Clemens comes back, your staff is probably second to none. Gota love the possibility of Clemens/Halladay/Harden at the top of that rotation.
What I would do. If you're looking to make a move, I'd say use Hudson as the main focus of a package to get another closer, Benitez and Orvella are both low-tier closers, you should have a solid one. Also I'd try to get another bat in your lineup. If Edwin Encarnacion is availabe, pick him up, move Lee to your OF and use him as your Util. If not, try to trade for a mid-level bat, just to push you over the top. Neither of these are MUST-DOs, so if you want you can just ride with this team and expect a good season. Good luck.
