Weakness in your keepers may be overstating it, more like what do you need to dominate. Nice team
You may have too much speed (since the idea is to have just enough to get the max points each week), but that's an issue you can remedy with a trade later if you want. With 2B open you're likely to also get another speedster there as any with pop will be kept (Utley, Uggla), so you can get away with ignoring speed at your open positions if that luxury presents itself during your draft.
Pitching should be your biggest focus since you're counting on Sheets to be your ace if he's healthy. You can use a good bopper at 3B or RF, too, but you're off to a nice start.
