Having missed out on Michael Johnson, the Vikings could turn their attention to George Selvie.

Selvie, who played for the Cowboys in 2014, has been on their radar since last week. It's not clear if the Vikings will have him in for a visit, but he's one of better free-agent defensive ends left.

So who exactly is George Selvie? The journeyman defensive end has been with five teams since the Rams took a seventh-round flyer on him in the 2010 NFL draft. He has played for the Rams, the Panthers, the Jaguars, the Buccaneers and most recently the Cowboys in 2013 and 2014.

The 28-year-old finally settled in as a starter with the Cowboys, starting 29 of his 32 games there. He had 10 sacks the past two seasons with the Cowboys, but pass-rushing isn't his strongest suit. He is a reliable run defender who Pro Football Focus graded as the 14th-best run defender among 4-3 defensive ends last season. He ranked 16th the previous season, according to PFF.

Selvie has predominantly been a left defensive end — Johnson is a right end — so if the Vikings decide to take things to the next level with him, it's likely because they can envision him rotating with veteran Brian Robison at left end. Robison turns 32 next month and Scott Crichton, drafted in the third round last year to eventually replace Robison, did not play much on defense last season.

The Vikings struggled to defend the run last season, allowing 4.3 yards per carry, 24th in the NFL.
