The starting pitching will be much better than it was this year. I believe that Heaney and Skaggs will be better next year, this year was the first year coming back from TJ surgery. Trop should be better next year as well, but I don't know what his ceiling is.
Barria is young and was treated with kid gloves (and rightly so) by Scioscia this year. He should easily develop into a 7 inning pitcher next year. That with Heaney and Skaggs healthy will help the pen immensely.
If Shoe is back and Pena is able to duplicate what he's doing this year, I think starting pitching will be fine.
