It's not about Smith's age. As a starter, he was not very good. A 5.32 ERA, 1.606 WHIP, and a K/BB of 1.79 just aren't very defensible. But over the last three years as a reliever, we're looking at a 3.22 ERA, 1.232 WHIP, and a K/BB of 3.55. So, I think that tells the tale. Now, the 12.2 K/9IP Smith has posted tells me that the best route to maximize his value is to make him the closer by trading K-Rod this off-season. K-Rod should net a top 30 prospect (albeit closer to 30 than 1). Buy out his arby years, and have him close for two or three years, rack up a few dozen saves. Then the Brewers can flip Smith for a higher return than if he is perceived as a LOOGY/middle relief guy. I hope you mean Top 30 as in an organizations Top 30...not all of MLB.
