Mike Mitchell: 80 tackles, 1.5 sacks, 3 interceptions
Once seen as a major draft reach, 2009 second-rounder Mike Mitchell finally lived up to his billing in 2013. Of course, some of that can be attributed to playing behind an exemplary front seven.
In Pittsburgh, Mitchell won’t be afforded that luxury. As a result, his tackle numbers should increase (Ryan Clark has posted at least 100 in each of the past three seasons), but at the expense of a few splash plays.
Cam Thomas: 30 tackles, 2 sacks
News from the Pittsburgh Post-Gazette's Gerry Dulac that the Steelers signed 330-pound Cam Thomas to play the five technique came as a surprise to many, but as of now he may be the team’s best option across from Cameron Heyward. Barring a Brett Keisel return, he’s easily the most experienced.
If Thomas earns the starting role, eye-popping numbers shouldn’t be expected. Like most other 3-4 defensive ends (J.J. Watt notwithstanding), Thomas’ impact should be seen more in the players behind him.
Arthur Moats: 40 tackles, 4 sacks
The versatile Arthur Moats has experience both inside and outside and the Steelers will likely use that to their advantage. It’s not out of the question that Moats could start over Vince Williams or Jarvis Jones either.
However, these projections assume that, as SBNation’s Neal Coolong suggests, Moats will primarily be a backup outside linebacker. If so, numbers on par with what Jason Worilds posted as the third outside linebacker are a reasonable expectation.
Brice McCain: 20 tackles, 1 interception
As with Heyward-Bey, Brice McCain is a free-agent signing whose spot on the team is not yet assured. Presuming he does land a spot on the final roster, he'll only be a fourth cornerback.
Even still, there’s no such thing as too many serviceable cornerbacks in today’s NFL. As that is the case, McCain should see some playing time and maybe even manage a pick or two.
