The storyline
Two of the league's most physical teams meet again after a heck of a season opener in 2009 (Troy Polamalu got hurt, etc.)

The Steelers are short of tackles and the Titans have a young, active defensive line. If Pittsburgh manages to win this, again under Dennis Dixon, it would be huge. CJ2K goes for his 13th straight 100-yard game against an elite rush defense.
