Andre Patterson's process for teaching new players the Vikings' defensive line techniques includes a video breakdown of position-by-position techniques that goes back nearly 25 years.
"Well, I've got John Randle on there. I've got Leon Lett on there," said Patterson, the Vikings' assistant head coach. "I can go on and on. I've got Henry Thomas on there."
Patterson also has Sheldon Richardson on there, from his 2018 season with the Vikings. When the team brought Richardson back from Cleveland for another stint in Minnesota on a one-year, $3 million deal, Patterson needed time to reintroduce the defensive tackle to how the Vikings rush the quarterback and play blockers.
