Well, let's see. The National League average starter put up a 4.65 ERA last year. The average National League reliever put up a 4.06 ERA. So 200 innings of 3.75 and 80 innings of 4.06 gets you a 3.84 ERA out of both players combined. 80 innings of 2.00 and 200 innings of 4.65 gets you a 3.89 ERA overall. Of course, having those good innings all come in close games does give an extra benefit to the setup guy. At the same time, you have to add in that an average reliever costs you probably 1 million dollars and can easily be replaced if something goes wrong, while an average starter is going to cost you 3-6 million dollars at least and if they bust, they're much harder to find a replacement for. If I could lock in either of those two choices, I'd go for the starter. There is so much more flexibility in a bullpen to find a few good players and use them in all the important situations. In the Cubs case for example, Marmol going into the rotation moves Howry into Marmol's sport, Wuertz's into Howry's, and Eyre into Wuertz's. The guy who would replace Marmol wouldn't even have to be that good, because he'd be getting most of the mop up innings anyway. Of course, I have my doubts that Marmol could produce that much as either a starter or do it again as a reliever, but that's another discussion entirely. I'd take him as a reliever, simply because he's comfortable as a reliever. And if I am mistaken, he was developed a s a reliever in the minors. Which means, even if the Cubs wanted to move Marmol into the rotation, they'd prolly have to send him down to AAA for about a month or so, to stretch out his arm, and fine tune his mechanics. So nothing only would the Cubs be down an outstanding bullpen arm, but an outstanding arm all together for atleast a month. At this point, I much rather have Marshall/Gallagher/Veal/Smardz have the shot at starter in front of Marmol. Middle of the season is not a good idea to experiment. If the Cubs believe Marmol can be an outstanding starter, then let him make the transistion to starter in the OFFSEASON, not the middle of the season. Nonetheless, Piniella absolutely trusts Marmol in his current role, and thus is NOT about to move Marmol out of that spot. He was a starter in the minors. You're not going to make him a starter right now, but it's something I wish they would have done in the offseason.
