A league source tells the National Football Post that while line coach Larry Zierlein has been bounced from Pittsburgh, offensive coordinator Bruce Arians can return to his post under coach Mike Tomlin in 2010 if he desires.

Arians and the offense came under fire during the season, particularly as the season unraveled during the second half of the season. But the job is his if he would like to come back. Of course, he’ll be working with a new line coach, but the Steelers need to revamp what they were doing upfront to make some improvements after they went from winning the Super Bowl to finishing out of the playoffs this season.

Stay tuned.
