Matt Feiler agrees to three-year deal with Chargers?

Minutes after Bud Dupree agreed to terms with the Titans, the Steelers lost another of their free agents. Matt Feiler agreed to terms with the Chargers on Monday night, Adam Schefter of ESPN.com tweets.

The four-year veteran will sign a three-year, $21 million agreement with the Bolts. Feiler has worked as a Steelers starter for the past three years.

This move comes hours after the Chargers agreed to terms with Corey Linsley on a center-record contract. Feiler figures to have a spot on the Bolts’ starting O-line as well. Where he lands will be interesting. Feiler has seen time at both tackle and guard, taking over for Marcus Gilbert at right tackle and spending time on Pittsburgh’s interior line as well. Pro Football Focus graded Feiler as a middling guard starter last season but has charted him as an upper-echelon lineman throughout his career.

With Los Angeles, Feiler’s spot would seem to be guard. The Chargers paid up for Bryan Bulaga at right tackle last year. They just cut guard Trai Turner and have fellow guard Dan Feeney set for free agency. Feiler’s position notwithstanding, he represents more resources thrown into protecting Justin Herbert.

The Steelers have brought back B.J. Finney but have some major questions up front. They have now lost Feiler and perennial Pro Bowler Maurkice Pouncey, and left tackle Alejandro Villanueva may well be on his way out as well.
