Sheldon Richardson showed his value in Mike Zimmer's defense in the first quarter of his first game in a Vikings uniform. The veteran defensive tackle turned the 49ers offensive line into mincemeat on back-to-back plays.
First, he drew a holding penalty when the left guard grabbed him by both shoulders and tackled him. Richardson flipped sides with nose tackle Linval Joseph on the next play and created destruction there, too.
He shoved the right guard backward, then shot through the gap between the center and guard to pressure quarterback Jimmy Garoppolo.
Statistically, Richardson shared a sack with Everson Griffen, but the pocket collapse was the product of Richardson's bull rush up the middle.
"I told him I hadn't seen that guy before," Zimmer said after Richardson's dominating debut for the Vikings.
If Richardson continues to perform like that guy, he likely will be the next guy to receive a lucrative extension from the organization. Through two games, he has been one of the defense's most disruptive and productive players.
"He's motivated," Griffen said. "I don't know if [defensive line coach Andre] Patterson is getting in his ear, or Coach Zimmer is getting in his ear."
Perhaps he recognizes an obvious need and opportunity. Zimmer has long coveted a pass-rushing, three-technique tackle. That position is one of the most vital in his scheme, and Zimmer has a certain vision for what he wants and how it should be played.
