What about Eck? He's bright, a HoF'er who started and closed, knows pitching and the game well, and played a ton under one of MLB's premier managers with LaRussa.
Is it that he doesn't want to manage, or that he wouldn't be the puppet the FO wants? Certainly he'd clean up the clubhouse issues and run a tight ship, but is it that he's too upfront and outspoken for the brass?
