Well, your OF is definitely set!
I think you are going to need to make a few trades to pull this team together. You are over-loaded at OF and 1B (a total of 8 players). I can't tell how much of a problem this is without knowing the position settings for your league, though. If your league has 5-OF, 2-Util and and a CI position, you aren't in terrible shape. But if you have Yahoo's standard set-up of 3-OF, 1-Util and no CI, then you are in big trouble. (The following advice is all based on the assumption the you are using Yahoo's basic 3-OF, 1-Util, no-CI setting)
You have huge holes in 3B and SS. And your Starting Pitching is also very suspect. On top of all that you have decided to punt saves.
Theriot might have a break-out season...and in a 14-team league SS is particularly thin, so I think you have to stand pat at SS for now while you address the other issues. So your first order of business should be to trade one of your OF's or 1B's for a 3rd Baseman. As long as you get fair value in return, I don't thinlk you can consider any of your OF's/1B's as untradable.
I would also be a bit concerned if my best SP is Kazmir. Kazmir and Lackey are both solid pitchers, but not great (even in a 14 team league, they are both #2 starters). Bedard has some risk, but he also has a big upside (Bedard = #3 starter). But after that, your pitchers are full of question marks. Pettite/Wang/Buehrle/Perez/Carpenter/Arroyo are all #5 starters at best. A few have limited upside, but they all have huge risk/downside. Accordingly, I would also trade another one of the OF/1B group for another #2 or #3 Starting Pitcher. You might be able ot package Wang with an OF/!B to improve the quality of SP you get back.
I'm sure in a 14 team league the waiver wire is pretty dismal. But I would consider the following guys on your team as expendable if you can find any free agents with some real upside: Clint Barmes and Bronson Arroyo.
So the bad news is you punted saves but you still have several holes to fill. The good news is you are so loaded at OF and 1B that you have the trade bait available to fill those holes. Just a warning, though, you will need to make any trades you make count. Make sure you get full value in return. If nobody offers you a fair trade pre-season. you are better off waiting for the season starts and other teams have injuries or guys in a slump.
