It's just that the Steelers have depth at safety. That's all Troy!
As far as the linemen go, on defense an injury would figure to be plugged by last year’s top draft choice, Cameron Heyward. Heyward may even wind up starting somewhere by season’s end. There is depth on the defensive line.
There’s also depth on the offensive line following the resigning of Max Starks and the drafting of David DeCastro and Mike Adams.
Furthermore, there’s always the mindset that a team can find a player to fill in on the offensive line.
Ramon Foster wasn’t even drafted coming out of the University of Tennessee in 2009. He’s started 22 games over the past three years and the Steelers have won 35 games in that time.
Running backs? Even if Issac Redman gets hurt, Jonathan Dwyer rushed for more than 100 yards against Tennessee last season.
John Clay showed promise and could be a bowling-ball type in limited action, and Chris Rainey comes off a fine collegiate career at Florida. There’s plenty of depth at running back.
Leonard Pope, a clutch receiver with more than 100 career receptions, is a nice pickup to back up/play opposite tight end Heath Miller.
There’s a school of thought that strong safety Troy Polamalu could be a player the Steelers can’t afford to miss, but his gambling cost the Steelers their playoff game against Denver. In his 10th year in the league of playing high-intensity football, one must wonder if he is irreplaceable or about to drop off.
The Steelers lost Rod Woodson at cornerback for the entire 1995 season and still made the Super Bowl that year. Could Pittsburgh go as far with Ryan Clark, and Ryan Mundy starting at safety, if worse came to worst?
It may be harsh to say that kickers are a dime a dozen. This writer, after all, remembers David Trout. But the Steelers replaced punters in 2008 and won the Super Bowl and kickers in 2010, and made it to the Big Dance. Why wouldn't 2012 be the same?
