Very nice OF, shaky IF. Is there no better option at 1st than Phillips? I drafted Phillips, but I think his only value is at C. If Ensberg and Berroa play like they did last year (with Ensberg not platooning), and Giles can come close to what he did, your hitting will be fine. However, I'm not sold on Giles, and the other two could easily slump.
Your first two pitchers are good- I think they will both pitch better than they did last year- but it's steeply downhill from there. Weaver needs to pitch to his potential and Affeldt needs to stay away from blisters for you to have a shot at most categories. Brazelton is garbage, even in a 16 team league. You'll be hurting for saves, even if Nen is healthy.
The only thing I'd look at right now is 1b. For everything else, it'll be hard to do anything because with 16 teams there probably aren't many options on the WW. Just wait until the season starts.
