Irons began his career at Butler County Junior College before landing at Auburn in 2004. He sat out that year with a knee injury, but recovered enough to earn All SEC 2nd team honors a year later after finishing with 48 tackles, and 11 passes defensed. As a senior, Irons had 40 tackles and two picks on the year.
David Irons is a very solid cover corner. He has the quickness to stick with receivers in and out of their breaks, and the speed to run with them down the field. He is also tough and aggressive, and willing to support the run.
Irons has only average size, and can lose out against bigger, more physical receivers. It also hinders his ability to be a force in the run game, despite his willingness to come to the line. Even though he has good cover skills, Irons has never been the playmaker a top tier corner should be. He had just two picks in two years at Auburn, and needs to show better skills at making a play on the football.
Irons has seen his stock rise in the post season, and he now grades out in the same area as his brother Kenny. His lack of playmaking ability may hurt him though. He could hear his name called in the late second, but should be gone in the third at some point.
