Christopher Carter of the Pittsburgh Post-Gazette, hosts the Locked on Steelers podcast, and is joined by Alan Saunders of SteelersNow.com.

The Pittsburgh Steelers' run game still hasn't taken off after four weeks as the young offensive line faces growing pains. Christopher Carter and Alan Saunders assess how Zach Frazier, Broderick Jones and the line have played, and the impact of James Daniels being out for the year with an injury. But also, how can Arthur Smith scheme up better opportunities for the Steelers' run game for Najee Harris?

And, it's Stars and Skulls grades day, where several players receive skull grades for their parts in the first loss of the season. But who got the harshest marks? Chris points to the defense, particularly Joey Porter Jr., Patrick Queen, and others. Also, what was Justin Fields' final grade after scoring three touchdowns?
