The Boone supporters seem to be saying "Ok, we know that Boone is not a solid manager, but managers don't win games, players win games." This is really missing the point. The fact is that each part of a team affects whether a team wins or loses ballgames, from the front office (Lindner-ugh) to the last guy on the bench (Castro-ugh). Why not strive for excellence?
The evidence would suggest that the baseball industry does not hold Bob Boone in very high regard as a manager. He was not offered another management job for over 3 years after he was fired in KC. Hell, he was 3rd or 4th on the Reds list when he did get an offer here, and his biggest selling points were that he was 1. Cheap, 2. Cheap, and 3. Very cheap. After his tenure here I would be shocked if he is ever offered another management job at the major league level. If the Reds do not contend next year, he will be out of a job.
