Pittsburgh’s depth was tested in 2012 when it lost numerous starters to injuries.
They failed the test.
Depth should be an even bigger concern in 2013 as the Steelers lack experience behind the starters along the offensive line, in the defensive backfield and at inside linebacker.
Kelvin Beachum is a do-it-all offensive lineman who can play both guard and tackle spots and was getting snaps at center during the team’s offseason workouts.
Besides Beachum, the only lineman likely guaranteed a spot is John Malecki, who can play guard and center.
A number of players including Guy Whimper, Joe Long, Nik Embernate and Mike Golic Jr. will be some of the players competing for a spot.
In the defensive backfield, the Steelers are set with their top five.
Ike Taylor, Cortez Allen, Ryan Clark, Troy Polamalu and William Gay will form a formidable secondary that should once again be one of the better units in the league.
Curtis Brown will look to improve after two disappointing seasons at cornerback while Robert Golden and rookie Shamarko Thomas will compete for playing time behind the starting safeties.
Besides the offensive line, the thinnest area of the roster is at inside linebacker.
Larry Foote will once again start alongside Lawrence Timmons, but the Steelers may have to depend on rookie Vince Williams as the top backup.
It is unknown when Sean Spence will be ready to return and Stevenson Sylvester was shifted to the outside during minicamp.
What we know now is that there is a lot of unproven depth and there will be plenty of opportunities for the younger guys on the roster to make an impact as a backup.
