to me Bobby Cox I mean come on 2,501 wins a regular manager doesn't even come close to that!he was Manager of the ano four times (3 times NL w/the Braves of course!) and (1 time AL with the Jays) he was even a General of Manager of the Braves! even especially during the 1990 season he fired the Braves current manager (being the GM) and appointed himself as manager! the teams combined made it to playoffs 16 times! he's also fourth as of now on the All time Wins! I know there are lot of other great Managers like Tony La Russa,Connie Mack,John McGraw and others!
Buck Showalter. He's brought back so many teams, most recently the Orioles. Look at them! They were once a losing team, bottom of the division, and now they are at the topo, início of the Wildcard. All thanks to Buck. He once did the same for the Yanks. BUCKle Up!
