It doesn't work like that with relievers, though. It would be easier if it did, but it doesn't. An guy who is impregnable one year is highly permeable the next. One year Doug Sisk is the Man Without an ERA, the next year he can't keep his slider down. One year Randy Myers is throwing batting practice, the next he's got the batters in tears. Messy Fiasco to Jesse Orosco. Tug McGraw spent most of his "Ya Gotta Believe" year as the worst pitcher on the team. Couldn't be touched down the stretch, though. So you can't just say, "You failed, you're gone; you guys haven't failed yet, welcome aboard." You've got use judgment and shit, painful as it is to have to reinforce some of that judgment through bad results. But we've had mostly bad results through a bullpen merry-go-round for six years now. I don't know what to say, but I don't think cleaning house gets us forward. Part of Casey's gospel was that if you've got two good relievers, one of them will go bad on you the next year, so you'd better get a third. That's smart, but it's hard to apply in an era where teams put themselves in a position to need five-seven good relievers.
