12 teams H2H, 5x5.
Ordinarily I'd keep both Santana's, but since ES will be missing some significant time, I suspect you can probably pick him up later on in the draft. As injury-prone as they are, I think you have to keep both Furcal and Chipper, simply because of the positional scarcity.
The one wild card that I'm debating is Ian Stewart. I have a feeling he could have a good year, and in most leagues he qualifies at 2B - which is another shallow position. With every team keeping 10 players, I'm scared to see what the remaining talent pool will be at 2B, 3B, and SS.
