Only eight players wearing No. 99 have appeared in a regular-season game for the Steelers. The list of those who have worn it with distinction shrinks to just two: LB Levon Kirkland and DE Brett Keisel (no offense, Larry Ogunjobi).
Derrick Harmon is the latest Steeler to wear No. 99, and the team has high hopes for its latest first-round draft pick.
So does Keisel, especially since he and Harmon also share a position.
“I want him to take that number to the top and have a Hall of Fame career,” Keisel told Steelers Depot last week.
