You're pitching is excellent and I'm sure at the very least it's one of the top 2 or 3 in your league, perhaps the best. The offense, well not so much unfourtently. The outfield is pretty impressive, with Sizemore, Holliday, Quentin, N Cruz and Shin-Soo Choo. I'm a huge fan of Shin-Soo Choo, he is almost always never picked up and so you can snag him as a fifth/sixth outfielder in the late rounds. He has good upside. Unless a lot of guys get injured, then your main goal with your last outfielder, I believe, is to get one with a lot of upside. That's what he has, if he does what he did last year or even better, then you have a starting, very good quality outfielder.
Catcher is OK, 1st base is great, second is terrible, short stop if bad, and third base is bad. All in all, you have a slightly above average team. I suggest you trade Jake Peavy for a guy like John Lackey or Roy Oswalt plus a good second basemen like Kinsler, Phillips, or Roberts. I'm a big fan of Cano, but not many people agree wit me on him. You could also look for someone who for some reason got Hanley and Reyes/Rollins, or even a high quality guy like Jeter. After Rollins, there is a big drop off to Jeter, and then an even bigger drop off to Stephen Drew. You might also be able to get A-Rod, Aramis Ramirez or even the often underrated Chipper Jones.
