I am surprised by the talk of spending big for a top line starter. My impression of the trade with Oakland was that spending 20% of your payroll on someone who starts 33 games is an incredibly bad use of resources. Over a six-year deal you have an aging player, normal injury risk, a couple of years where nagging injuries may hinder performance, and maybe a year or two of unlucky BABIP. While it is important not to get carried away by Bosio magic, a lot he did for Edwin Jackson, the idea of getting 3 or 4 guys like Feldman, Hammel and Arrietta for the same cost and hoping to get one or two of them pitching like an ace every couple of years may be the way to go. We all know the variability of bullpen performance. Maybe the variability of starters only differs to a degree, and in the current pitchers' environment, perhaps the edge is in improving one's offense.
