Kevin Colbert is heading out the door. Who is walking to replace him is anyone’s guess. Pittsburgh cast a mile-wide net of candidates to be the team’s next GM, interviewing a whopping 16 men over the course of the offseason. Some names were familiar, including two internal candidates in Brandon Hunt and Omar Khan, long-time members of the Steelers’ front office. Some were former-GMs, like Jerry Reese and Rick Spielman. And some are external candidates with ties to Pittsburgh, just as Colbert had before being hired in 2000. One man in that camp is the Philadelphia Eagles’ Andy Weidl.
