The 37-year-old often was overwhelmed by younger, fresher defensive tackles. In the run game, he was a day late. Finally, the 6-foot-2, 308-pound Dietrich-Smith was inserted as the starting center and — as quarterback Aaron Rodgers often hinted himself — he showed signs of being the center of the future. Inside an ear-splitting Metrodome, Dietrich-Smith was the point man for a unit that generated 34 points and 405 total yards in the regular-season finale against the Minnesota Vikings. He was hardly the problem in the playoffs, teaming with Josh Sitton to spark a pair of DuJuan Harris touchdown runs.
