Vikings center Pat Elflein missed exactly 10 months of action while recovering from ankle and shoulder surgeries after Week 14 last season.
Since his return in Week 3 of this season against Buffalo, the second-year center has been part of an offensive line that has had several ups and downs as the Vikings have worked their way to a 6-6-1 record heading into Sunday's game with the Dolphins.
Elflein, a 2017 second-round pick out of Ohio State, said that at this point in the season the offensive line hasn't played to its potential.
"We need to be better, we need to be better," he said. "We need to execute better, tighten up on the details of the job and do a better job."
In the first nine weeks of the season, quarterback Kirk Cousins was sacked once in three games, twice in one game, three times in one game and four times in four games.
In the past four games against the Bears, Packers, Patriots and Seahawks, Cousins has been sacked twice in each game.
Still the Vikings rank 13th in quarterback hits and 19th in sacks allowed.
"I need to do better because it's not good enough," Elflein said.
