[1][2] David Whitehurst was the second quarterback in NFL history from Furman, a small Liberal Arts college.

Knowing that for obvious reasons, he couldn't wear number 15 for Green Bay, Whitehurst switched to 17.

In one of the best games of his career, Whitehurst completed 12 out of 23 passes for 108 yards and 2 touchdown, with zero interceptions in a 34–24 win over the Seattle Seahawks.

[4] Two weeks later, Whitehurst was the starter again, this time leading the Packers to a 21–17 win at home versus their long-time rivals, the Chicago Bears.

Whitehurst was released and he then signed with the Kansas City Chiefs to be a backup to Bill Kenney and to help mentor rookie Todd Blackledge.
