Baseball Prospectus has a two-part interview with Joe Maddon.  Here are the links:

He discusses statistical preparation, gut instincts, and more.  It's not clear on an everyday basis that we miss him, but having a mind like that around sure didn't hurt, either.  I hope the D-Rays are patient enough with him to allow him to turn things around there.
