If we're going to talk replacement level, let's look at the stats that tell us what replacement level is. Last year, Suppan's VORP was -8.2. Let's compare that, though, to Bush's -14.8 and Parra's -23.9. Looper wasn't much better, at -5. There seems to be the idea that Suppan was our worst pitcher last year, but the numbers simply don't back that up. That doesn't make him good. He was still bad. But only Gallardo was clearly better last year, and we can't say with authority that Bush, Parra, or Narveson will outperform him based on the numbers. I will say though, that if he's pitching for a spot in the rotation right now, he's sure not making a very convincing case for himself.
