I think you have a lot of questionable hitting talent. We all love sleepers, youth and bounce back players, but seems too unproven. Will Pods bounce back or Sosa? Shef you can count on and I do like Morneau and Estrada, but not as the nucleus.
Get some proven bats. Like your top 3 starters, though. Don't know about the depth though. Can't see you winning it as it stands now.
