I'd have to think long and hard about it, but ultimately I think I would take Konerko over Lawrie, with Hosmer close in the race, too. I've profited too much from Konerko's under-the-radar skills over the past few season to discount him now, even if age is a factor. I know picking him may be shortsighted, but he is a proven commodity, and that is what I am looking for. Lawrie and Hosmer are still "high potential" guys who have not yet started producing at the level Konerko does. You get SB with the other two that you don't get with Konerko, but he comes out on top in AVG, HR and rbi.
As for the arms, I agree with others who say that Moore and Medlin are the ones. Moore started really putting it together in the second half. I'll be targeting him next year.
