Mike Harris was the team’s starting right guard in 2015, while Brandon Fusco was moved to the left side. Last season, Harris missed the entire season due to an undisclosed non-football injury. Fusco was moved back to the right side, but his struggles continued.

Both Harris and Fusco were nearly released two months ago. Head coach Mike Zimmer was asked on Wednesday about the offensive line.

Free agent additions Riley Reiff and Mike Remmers will be the starting tackles with Boone staying at left guard. At center, it could very well be Joe Berger again. Another option could be to move him at right guard and have Nick Easton start at center. Berger has shown that he can play multiple positions on the line.

Easton appeared in 11 games last season, starting the final five games. Berger missed two of those games with a concussion, but was then put in at right guard during the final three games. Easton did not appear in any games in 2015.

Berger has been with the Vikings since 2011. He started in 18 out of 61 games from 2011-2014 before becoming the full-time starting center in 2015 when John Sullivan was out the entire season with a back injury. Sullivan was cut last year.

Given that Berger will be 35 in May, this could perhaps be his last season. He had a decent season after having a very good 2015 season.

There is a good chance the Vikings could draft a guard at #48 and move him into the lineup. Indiana guard Dan Feeney and Ohio State center/guard Pat Elflein could both be available.

Another option could be Jeremiah Sirles. He was re-signed after starting in 10 out of 14 games played last season, one at left guard and nine at right tackle.

“There’s going to be competition, and you look forward to competing and trying to rise to the top,” Sirles said. “I played all along the line last year in (spring drills) and that is where I staked my claim. I’m a guy that wherever they want to stick me, I’m going to battle it out for a starting spot.” (St. Paul Pioneer Press)

The offensive line will be the biggest question mark entering the season for the third year in a row, but it is certainly nice that they have more talent and depth added to the unit.
