Best and worst case for 17 players 

Drafted: Round 1, No. 21 overall

Best-case scenario: The coaching staff set a high bar for Harmon — announcing he would start all the way back in June — but he continues to deliver when the real games begin, adding an extra dose of juice and toughness to the Steelers’ defensive line. Pittsburgh has a bigger version of seven-time Pro Bowler Cam Heyward on its hands.

Worst-case scenario: Heyward’s contract dispute with the Steelers drags into the season, and his absence pushes Harmon into a role he’s not completely ready for yet. He fails to stand out in any one area and seems to be missing an elite trait needed to cause chaos up the middle.

Projected stats: 40 tackles, 7 tackles for loss, 3.5 sacks.

EDITOR’S UPDATE: Harmon suffered a knee injury in the Steelers’ final preseason game, which was held after these projections were published. He’s been diagnosed with an MCL sprain and is expected to miss about a month, per NFL Network Insider Ian Rapoport.
