White closed out his college career as the only quarterback in FBS history to start and win four bowl games. He also set the FBS record for career rushing yards by a quarterback (4,480 yards).
Following his senior year, White competed in the 2009 Senior Bowl, where he won game MVP honors. He passed for 95 yards and a touchdown and added 31 rushing yards on three attempts.
White was drafted in the second round (44th overall) of the 2009 NFL Draft by the Miami Dolphins. Before the 2009 season, White signed a four-year contract with Miami. White played quarterback for the Dolphins as a rookie, though most of his plays came out of Miami's Wildcat formation. As a rookie, White saw action in 13 games, rushing 21 times for 81 yards. He was 0-for-5 passing. White's most extensive action came in Miami's regular season finale against the Steelers, when he replaced the injured Chad Henne, before suffering a concussion. He was in a helmet-to-helmet collision with Ike Taylor, and had to be carted off the field.
