Fredi Gonzalez is a perfect fit. He literally called Cox, Wren, and other members of the Braves org the day the dipshit from the Marlins fired him.
My sleeper pick is Eddie Perez, but I have no idea what he'd be like as a manager. I just think it'd be funny. The guy was Maddux's personal catcher and has been the bullpen coach for a while, and has been managing for a while in the winter leagues. Would be interesting to say the least, and vastly preferable to TP, in my opinion.
