Im probably in the minority here, but Mazzone is not my first choice. My first choices are Righetti and Guidry. Mazzone is a Brave and he should stay that way. Him and Bobby Cox work magic together and I think that has somethign to do with their success.
Both Rags and Gator know what it's like here, both are very well liked and respected here, and I think both would do a good job here.
What exactly does a pitching coach have to do to determine if he is good or not. Personally, if great pitchers (Clemens, Wells, etc.) are stating that he is the best that they've ever had then I will go with them.
Im not saying hes the best oitching coach ever, because clearly he's not. He wasnt even the best pitching coach of the last 10 years, that was Mazzone without a doubt, but Mel is nowhere's near as bad as you guys make him out to be.
