Pittsburgh Steelers updated Team Outlook after backup Quarterback Mitch Trubisky agrees to a 2-year extension with the team. Trubisky began last season as the starter, starting 5 games for the Steelers before being replaced by rookie Kenny Pickett. Trubisky will be the backup again this season as the Steelers are set on turning to Pickett, but Trubisky will be ready in case of emergency and to help guide Pickett through the rigors of being an NFL QB.
