Here's the conundrum as I see it.
3B and SS are set, like it or not (until Lewis is hurt, but then you are playing a backup, you aren't bringing in a starter while you have Lewis and CC). 2b is Keaschell, Culpepper, or Lee. C is Jeffers and there isn't one out there you can bring in and hit most likely. CF is Buxton.
that leaves LF, RF, 1B. Now, their top prospects are Jenkins, EmRod, and GG in the OF. And they have Wallner and Larnach. Plus Martin, Eeelse and Keaschell as backups.
What do you trade FOR? Because they 100% need more pre-arb players (EmRod and Jenkins and Culpepper and Lee). It's hard to see trading for an OF at this point. Or 2B.
