Can you imagine Terrell Suggs playing strong safety not long after being named Defensive Player of the Year?

Or even J.J. Watt lining up at cornerback?

What about Charles Woodson at nose tackle?

Seems about as silly as having a finally healthy, barely-over-200-pound, 32-year-old Troy Polamalu play inside linebacker three years after being named the best defensive player in the league at a strong safety position that he revolutionized.

Now, what very well could be the last go-around for Polamalu with the Steelers as he could be a salary cap casualty in March, it's coming at a position that he has rarely played before and is grossly undersized to be truly effective.

As a strong safety, Polamalu is an All-Pro.

As an inside linebacker, he's not.

Playing both is taxing.

“Especially how much we've been using it,” defensive backs coach Carnell Lake said. “It requires you to be mentally tough because you are preparing for two different spots which require two different skill sets. On top of that, the physical stress on your body in playing that close to the line all of the time really takes a lot out of you.”

Polamalu played 30 snaps at inside linebacker in the nickel package last week. It has been more some weeks and less others, but ever since the bye, Polamalu has played linebacker every game.

“Honestly, I like where the action is,” Polamalu said. “I will do whatever the team needs me to do.”

Decimated by Larry Foote's season-ending Week 1 arm injury, the Steelers tried other alternatives before turning to Polamalu. They tried journeyman Kion Wilson and then rookie Vince Williams before considering the final alternative — Polamalu.
