I think people are missing the correlation between expected future performance and salary when trying to find evidence that teams stick with bad players when they are paid more. They are paid more because of past success. That's why you determine who should start based on all the information, not just the results of a few starts. Now, Suppan's projections were pretty bad going into the season. An ERA of 6 for half a season will probably be enough to bump his projected ERA over the projections for the alternatives. As it stands, I'm not sure if the Brewers even have a better alternative, though. McClung perhaps, but that's about it, IMO.
