I think the young starting pitching would look a lot better with a lights-out bullpen. I'd sign one 200-IP solid veteran starter, then try to put together a really tough bullpen. I guess Morgan and Neris belong, and moving one or two of the young starters (Velasquez?) with high strike-out numbers and two good pitches would help. Then you can buy a couple of good to very good relief pitchers, who aren't super-expensive due to their position. Then the young starters can concentrate on getting 5 or 6 good innings and handing things off.
I know that is anti-analytical thinking, but the value of good relievers with a young staff is the new market inefficiency.
