Bush would be someone that hasn't changed since Maddux left he is still the same pitcher as he was when Maddux was here. If you throw out last years injury plagued year and use this years stats with Peterson you will see that his stats are about the same as they were when Maddux was here. Villanueva is also doing better this year with Peterson than he ever did with Maddux. Now for Parra the book is still out on him. Last year was more of a precursor to what was happening to Parra at the end of the 2008 season. During the end of the 2008 season Parra was burning out and was showing signs of being what he was doing in all of 2009. You can also file Gallardo as being the same pitcher as when he was with Maddux as when he wasn't with Maddux though 1-years worth of stats really isn't fair for either side of the coin here nor does it really paint an accurate picture. I believe pitching, hitting, fielding, running, etc. coaches are just scapegoats for fans in baseball and nothing more they are also scapegoats for managers and GM's also.
