For the first time in over two decades, the Pittsburgh Steelers’ defensive linemen are being coached and trained by somebody other than John Mitchell, who occupied that post from 1994 through the 2017 season. He was preceded by Joe Greene, who was on the job when Mitchell’s predecessor, Karl Dunbar, was drafted by the Steelers in 1990.
Not to worry, of course, because Mitchell did get to teach Dunbar as a college player at LSU. He spent years there before breaking into the NFL in the early 1990s, first with the Cleveland Browns, and then for the rest of his time at this level, in Pittsburgh.
