You have a incredible pitching staff.
I think you're vunerable at C, 2B, and SS. I don't like Jeff Kent at 2B, and Kinsler looks good, but will bat down in the Texas order, and may not start consistently. I think Tejada is in for a bad year. I would try to get a better SS or 2B.
Perhaps pair Kent and Escobar and get Figgins or Utley at 2B. Figgins would be nice from an SB perspective, as your team lacks SB. Utey look like a stud 2B of the future. You might have to give up more in a keeper in get one of those guys.
