The Minnesota Vikings have thrown their hat into the free agency ring, signing long time Tennessee Titans safety Michael Griffin this evening. Griffin, drafted 19th overall in 2007, has been with Tennessee his whole career and missed just 3 games in that entire span. His best season came in 2008 when he finished with 7 interceptions, 55 tackles and was invited to the Pro Bowl. Since then he has been a solid, if unspectacular, presence in the Titans defensive backfield. He added a second Pro Bowl appearance in 2010 but has enjoyed a largely quiet career in Tennessee. By joining the Minnesota Vikings Griffin is likely going to have to change positions if he wants regular playing time. With the Titans he was the primary free safety, playing deep and in space frequently. That role is filled, and expanded on, by the wonderful Harrison Smith in Minnesota. The other safety, Andrew Sendejo, signed a 4 year extension just last week so quite where Griffin fits in the Vikings plans is a mystery. Although when you face Aaron Rodgers twice a year you can never have enough defensive backs. It’s likely that Griffin will be a situational player rather than every down starter, but his experience as a deep safety can be used creatively, allowing Smith up to play a free role in the defense, roaming around like Troy Polamalu and Ed Reed, or just let him play closer to the line of scrimmage and get involved against the run. Either way, Griffin’s days as a starter are probably done, but so are his days sitting at home come the playoffs. The Vikings made other, more minor moves this evening, signing ex-Bengals linebacker Emmanuel Lamur and re-signing guard Mike Harris. An undrafted free agent, Lamur made his way in Cincinnati from the practice squad as a rookie to a starting spot in his third season, starting 13 games in 2014. For the first time in his career he appeared in every game in a season in 2015, though he was demoted to a backup role. He’ll likely compete for a backup spot in Minnesota. Harris was part of an offensive line that this past season helped Adrian Peterson claim his third rushing title, and will help give consistency in protection for Teddy Bridgewater.
