Mullen spent two years at Bowling Green where he tutored Omar Jacobs and Josh Harris, the school's most productive quarterback. During those two seasons Bowling Green threw for 5,145 yards and rushed for 1,482 yards.
Smith finished 4th in the Heisman balloting in 2004 and led the Utes to a 35-7 rout of Pitt in the 2005 Fiesta Bowl.
The rugged landscape of the SEC awaited Mullen as he took on the task of leading the Florida Gator offensive into a new era.
Dan inherited quarterback Chris Leak who after one year in the system won a BCS National Championship in 2006 and surpassed Heisman winner Danny Werffuel as the school's career leader in passing yards.
In 2007, Mullen adapted his system to utilize the full talents of Tim Tebow who went on to be the first sophomore winner of the Heisman trophy.
"He is very demanding as a coach," said Bob Redman of Fightin'Gators.com. "He can communicate what he wants to players in way they understand and they can buy into.
"He is a very disciplined coach and he is real meticulous. I have had to describe him in one word it would be meticulous."
Mullen's style of coaching appears to be a key component in the development of Florida junior quarterback Tim Tebow.
"You can really see a lot of development in him this year over last year especially as a passer," said Redman. "A lot of that has to do with how Dan has coached him to be."
Tebow was one of several recruiting battles Mullen won over the course of the past three years in Gainesville.
"He really did a good job holding off Tennessee for Demps," said Redman of Mullen. "Demps had offers from all over, but Tennessee stayed on him pretty much the whole time and Dan signed him."
Redman reports that Mullen is an impressive recruiter and that more times than not he lands his top targets.
"He presents himself well to the parents and the kids," said Redman. "The guys he really wants he generally gets."
