The Minnesota Vikings lost a number of key defensive pieces last offseason, something Mike Zimmer now admits he misjudged.

"I probably miscalculated some things going into the season when we lost all the guys that we lost the year before," Zimmer said. "We had a complete overhaul on defense, and sometimes that happens when you get to Year 7."

Minnesota lost Everson Griffin, Linval Joseph and three regular cornerbacks heading into the 2020 season.
