Even though the Pittsburgh Steelers recorded 37 sacks this season, we can't expect that kind of production next season, unless Dick LeBeau's defense gets younger and healthier.
James Harrison will be 35 years old this year and he's just one guy in Pittsburgh's front seven.
Casey Hampton is going to be 36, Brett Keisel 35 and Larry Foote 33. Breaking down the schematics of the 3-4 front, its basic objective is to get immediate quarterback pressure.
The result of that pressure makes it easier for the defensive line and inside linebackers to make plays. Combining the elements of Harrison's age and the fact that no player in Pittsburgh recorded more than six sacks and it's no surprise the Steelers failed to consistently force turnovers.
At some point, a defense must simply replenish its veterans with younger players.
Much of the Steelers' success this century is the resulting of continuity and developing players within the same scheme over time. Acquiring Spencer, though, will easily transition the dire need to rely on youth and develop the first and second-year guys.
Spencer's experience alone is appealing because not landing him increases the odds of 2013 echoing the 2012 iteration of the Steelers defense, in which a dominant pass rusher like Spencer was sorely missed.
