T.J. Watt has only ever known one defensive coordinator since being drafted by the Pittsburgh Steelers—and depending upon your interpretation of how their internal hierarchy works, that may or may not change this year.
Keith Butler, their nominal defensive coordinator over the past seven seasons, announced his retirement earlier this offseason, and the team recently named Teryl Austin as his successor. Austin, who has experience as defensive coordinator in other cities, has spent the past three seasons on the coaching staff as a senior defensive assistant. Watt shared his thoughts on that change with Mark Kaboly of The Athletic yesterday.
