Not only is Urban Meyer currently one of the top current head coaches in the nation, his coaching tree is the most impressive of any active head coach.
Meyer has been head coach at five different school: Bowling Green, Utah, Florida and his current position at Ohio State.
Dan Mullen, head coach at Mississippi State, stuck around on Meyer's staff from Bowling Green, to Utah and then to Florida before taking off for the head coaching job at Mississippi State.
During his time at Utah, Kyle Whittingham, Gary Andersen and Tim Beckman, respectively the head coaches at Utah, Wisconsin and Illinois, all coached under Meyer.
Then came Meyer's best years at Florida, and his staff benefited from the Gators' success.
Besides Mullen, Charlie Strong (Louisville), Steve Addazio (Boston College), Dan McCarney (North Texas) and Doc Holliday (Marshall) were all on his staff at Florida and are all current head coaches.
There are other current coaches with some up-and-coming talent on their staff, but Meyer's coaching tree is expanding and continues to be one of the best in the game.
