Who else would you put in the rotation? Gallardo and Estrada are/should be guaranteed spots. Fiers and Peralta probably grab two more. That leaves Narveson, Rogers, and Thornburg for the last spot. I don't think Tyler is ready, he wasn't very good in the majors last year and a full year at AAA wouldn't hurt. Rogers looked decent last year but I don't think you can count on him to be healthy for a full season, and even if he does stay healthy he didn't throw enough innings last year to start the whole season. When Rogers gets hurt he will be more easily replaced if he's in the bullpen rather than the rotation. Narveson isn't a great pitcher but he is more than serviceable. My only concern with him is his health after surgery. What I would really like to see the Brewers do is trade for one of the Dodgers starters that doesn't make their rotation.
