5. Former U.S. Congressman Heath Shuler
Heath Shuler was one of the best college quarterbacks of the 1990's, and was one of the reasons that Tennessee was enough of a player on a national scale to even think about recruiting then-number one high school prospect Peyton Manning.
Shuler re-wrote the Tennessee passing record book, before being taken by Washington in the first round of the 1994 NFL draft.
He struggled mightily, before moving on to New Orleans where things didn't look up for his career, and he retired in 1998, and quickly moved to politics in his home state of North Carolina.
Shuler, a democrat, served three terms in the U.S. House of Representatives, from 2007-2013, before redistricting made his constituency far more republican, and he retired, rather than seeking a fourth term.
