Source: Eagles agree to deal with former Chargers RB Mathews

The Philadelphia Eagles continue to add pieces in what has clearly become the wildest roster makeover in the NFL.

The latest big name added to head coach / personnel man Chip Kelly's nest? Free-agent running back Ryan Mathews.

FOX Sports 1 NFL Insider Mike Garafolo reported Wednesday that Mathews, a 2010 first-round selection by the San Diego Chargers, has agreed to a three-year, $11.5 million deal with the Eagles, with $5 million in guarantees.

As of Wednesday night, a contract had not yet been signed.

Mathews, 27, who played five seasons in San Diego after he was selected 12th overall, struggled with consistency, fumbles and health — as well as some lofty expectations as the running back expected to replace Chargers legend LaDainian Tomlinson.

Mathews never has started more than 14 games in a season, played 16 games just once and missed at least four games in three of his five seasons. However, in those two seasons with at least 14 starts, Mathews eclipsed 1,000 yards both times. After a career-best 1,255 yards on the ground in 2013, Mathews played in only eight games and ran for a career-low 330 yards last season, thanks in large part to a sprained MCL suffered in Week 2 against Seattle.

The Eagles were close to signing free-agent running back Frank Gore, but he had second thoughts and instead signed with the Indianapolis Colts. Several reports have Philadelphia still in mix to sign free-agent running back DeMarco Murray, with Garafolo tweeting late Wednesday that the team will host the 2014 NFL rushing champion on Thursday.

Philadelphia traded former Pro Bowl running back LeSean McCoy to the Buffalo Bills for linebacker Kiko Alonso earlier this month, creating the void in the backfield.

The move for Mathews comes a day after Kelly and the Eagles trading starting quarterback Nick Foles to St. Louis in exchange for oft-injured quarterback and 2010 No. 1 overall pick Sam Bradford. The move, which also involved an exchange of draft picks (though none in the first round), is believed by many as the precursor to another move aimed at ultimately selecting Oregon quarterback and 2014 Heisman winner Marcus Mariota, who played for Kelly when the Eagles' coach was still in charge of the Ducks.

On Wednesday, however, Kelly told reporters at a news conference while introducing Bradford, "We will never mortgage our future to go all the way up to go get somebody like that because we have too many other holes that we're going to take care of."

Count Garafolo among those in no rush to take Kelly at his word. Hear Mike's take in the video below:
