The other wide receivers on the roster bubble have been impressive through the first preseason game in their limited snaps. Players like J.D. Woods, Justin Brown, and even Derek Moye seem like they would be more productive additions to the Steeler's wide receiver corps than undrafted free agent Reggie Dunn.
Reggie Dunn's roster spot becomes an even longer shot with the looks that the Steelers staff have decided to give to running back LaRod Stephens-Howling and wide receiver Markus Wheaton as kick returner and punt returner respectively. He must beat out both Wheaton and Howling on the special teams while convincing the coaches to overlook his lack of receiving chops in favor of his special team production. Not an easy thing to do.
Despite these long odds, he has several things going in his favor. Gilreath's debacle at special teams last week should open Dunn up to receive returns this week at both spots. Mike Tomlin made sure to mention that the team would "continue to look at" Reggie Dunn this week before he and the other coaches "look at the snap count and see what's left for the rest of them." It is clear that the coaching staff hasn't closed the door on the possibility of Reggie Dunn being an explosive part of the special teams.
If Reggie Dunn can prove he is a step above the competition, particularly as a punt returner, he can make it tough for the coaches to cut him. By the same token, if he doesn't provide any "WOW!" moments in the next couple of weeks, it becomes very difficult to make a convincing argument to keep him.
Reggie Dunn has not been able to show any of the special teams ability in the pros that made him so dangerous in college as of yet. But he still has time before the season starts and just because he started out behind, doesn't mean he counted out of the race.
