Right now I would say you are not a contender. Giambi and Dunn together are going to kill your batting average. Add Ensberg to that and its a last place category. If Corey Patterson has a decent season then you should be fine in steals. Power department you are good in.
Pitching is a dl trip waiting to happen. Sheets, Harden, Colon, and Patterson are some of the most injury prone pitchers in the game. You are really skating on thin ice with them.
I would look to move Giambi or Dunn for a good starter. Then I would try and move one or two of your starters for a bat to replace Giambi/Dunn. Hopefully somebody will bite on Sheets or Harden after they have a good few outings.
