San Francisco 49ers DL Justin Smith makes a huge difference when he’s on the field. In the 49ers first 13.5 games of 2012, they allowed 3.02 points per quarter. After Justin Smith was injured (5.5 games): 7.0 points per quarter.

Our View: The 49ers signed Smith to an extension on Wednesday. The new contract likely lessens the 2013 cap hit for Smith and locks him up for the team’s Super Bowl window.
