"Frank Gore faced eight defenders in the box more than any other running back last season.
Simply put, defenses didn't respect Alex Smith. Gore saw a stacked box 42.3 percent of the time, nearly double the league average of 23.3 percent. He still averaged 4.71 yards per carry and ranked 10th in the league with 1,214 rushing yards. Now that Colin Kaepernick will have a full offseason under his belt as the starter and Anquan Boldin has been added, the passing game will have to be respected more. Gore should see more seven-man fronts in 2013."
