I've been making that comparison myself lately. When Melvin left the Rangers, they had by far the worst pitching in baseball. The Rangers had the worst team ERA in 2000 at 5.52 (KC was at 5.48). The next year, his last, their ERA was a ridiculous 5.71, nearly half a run more than the Rockies at 5.29. Right now, the Brewers have a team ERA 4.72 which is only better than the lowly Nats in the NL at 4.97. We are one Yovanni Gallardo injury away from overtaking them. Yo has an ERA of 3.08. The rest of the team has an ERA of 4.99. The next closest starter is Looper at 4.79. With no help from the minors on the way for another few years (provided they don't flame out) and Melvin's track record when it comes to acquiring starting pitching either in the FA market or in trades, I'm not optimistic about what next year will look like. I certainly wouldn't expect Melvin to get anything special back in a JJ trade given JJ's play and his contract situation combined with my faith in Melvin.
