The numbers have not been kind to the rotation - although all of them have pitched better than the results. Miley has not inspired confidence, I agree. Buchholz though, as maddening as he is given his stuff, has actually pitched largely decently. It is still reasonable to think the rotation can deliver something more like a 4.xx ERA than a 5.xx. If the offense does not perk up considerably though, it is a moot point.
The offense - it is hard to watch without thinking that this is something that one good weekend could fix.
