LVE had trouble establishing himself in Quinn's defense. He worked hard in the offseason to get back but it didn't look good at the beginning. However, he began to trend up late in the season.
This may have had something to do with some nagging injuries he had at the end of the 2020 season. When a player returns to the team after an injury that doesn't mean they are 100% as if they never had that injury. I think the same is true in Dak's case as well.
Anyway, LVE ended up with the 3rd most combined tackles and 4th most solo tackles.
Most ironic, LVE played great when the rest of the team played terribly. His three games in which he had double digit tackles were the three most devastating losses in 2021. Those games were the Broncos, Cardinals, and the playoff game against the 49ers.
