David Carr - QB - 49ers
As an assistant with the Raiders back in 2002, Jim Harbaugh reportedly graded No. 1 overall pick David Carr as a sixth-rounder.
While Harbaugh has stated his admiration for Alex Smith at least a half-dozen times since taking over as head coach, he's been coy on Carr's status. Based on his initial evaluation, Harbaugh will be looking to move in a different direction at backup QB.
