Rashard Mendenhall and Mike Wallace aren't the only Steelers unrestricted free agents likely to be in another uniform next season.
If the Steelers can somehow keep another unrestricted free agent aside from Keenan Lewis, it should be left tackle Max Starks. If they don't keep him, Mike Adams or Marcus Gilbert will try to protect Ben Roethlisberger's blind side next season. Is anyone really comfortable with that?
Unfortunately for the Steelers, they might not be able to keep Starks. Among their other unrestricted free agents are Larry Foote, Casey Hampton, Ramon Foster, Charlie Batch, Byron Leftwich and Will Allen. They might not be able to afford any of them.
The Steelers need to tender restricted free agents Jonathan Dwyer, Isaac Redman, Emmanuel Sanders and Steve McLendon, the heir apparent to Hampton at nose tackle, for $1.3 million each. That would give them the right to match any offer they get from another team. They'd get a third-round draft pick as compensation if they lose Sanders and a sixth-round pick if they lose Dwyer.
Linebacker Stevenson Sylvester is another restricted free agent, but he seems to be no more than a special-teamer, so they probably can get his services at a lower rate with someone else.
Guard Willie Colon is still under contract, but the Steelers should cut him and clear $1.2 million in cap space.
Because of injuries, Colon hasn't played a full season since 2009. He's scheduled to count $7.6 million against the cap in 2013, more than Antonio Brown, Ryan Clark and Brett Keisel. That doesn't make much financial sense.
The Steelers instead could start David DeCastro ($1.7 million) and Kelvin Beachum ($491,000) at guard. Both players still have to prove themselves, but at least the Steelers would be getting their money's worth.
