Looking down the road, the Reds have a saturation of starting pitchers. And this is a good problem to have, because we're not talking about Jimmy Haynes, Elizardo Ramirez, Eric Milton or Brandon Claussen. We're talking about honest-to-goodness pitching talent.
Perhaps, for now, it's true the Reds are missing a true "ace." However, that could be different in a year or two. Assuming Aaron Harang will not be brought back next year (and possibly Bronson Arroyo), who should the Reds cut ties with, presumably using as trade bait, to clear the path for a set rotation?
Consider not just who you like the least but who would fetch the best return.
