The Minnesota Viking continue to work towards upgrading the offensive line.

A day after signing tackle Riley Reiff, they have now signed Mike Remmers.

Remmers was a walk-on at Oregon State and undrafted in 2012. He was signed by the Denver Broncos, but was released week four of the preseason. He then spent the entire season on the Tampa Bay Buccaneers practice squad. He played one game with the San Diego Chargers in 2013. He was then released and spent the final month of the season with the Vikings, but did not play.

In 2014, he was signed by the Carolina Panthers off the St. Louis Rams practice squad during the season. He started all five games he played in that year.

The past two seasons he started in all 32 games. He spent most of this past season at left tackle when Michael Oher went down with a concussion.

His agent tweeted his excitement about the news.

Vikings wide receiver Adam Thielen was also a college walk-on, went undrafted and spent time on the practice squad.

The Panthers signed former Vikings left tackle Matt Kalil yesterday. Oher is expected to be moved to the right side.

He struggled last season at left tackle, but has been decent at right tackle. Pro Football Focus rated him at 66.1 this past season, but 72.1 in in 2015 and 72.8 in 2014.

Remmers will likely start at right tackle with Reiff starting at left tackle.  Neither may ever make it to the Pro Bowl, but both will be clear upgrades to this team. The offensive line has been a huge weakness the past three seasons and they know that if want to compete for a Super Bowl, that needed to change.

If the offensive line was even slightly better the past three seasons, they could have possibly won two more games in each of those seasons. Last season they went 2-4 in games decided by six points or less.

You can bet Sam Bradford is especially thrilled about the new additions. He not only will take less hits, but will also now have more time to target Stefon Diggs, Adam Thielen and Kyle Rudolph.

Every upgrade helps.
