Former LA Chargers that could come out of retirement: 3. Ryan Mathews
Just like everyone else on this list outside of Eric Weddle, Ryan Mathews was marred with injuries during his playing career and if he did not have to go through the laundry list of injuries that he did then he likely would still be a running back in some capacity in the NFL.
He definitely would not be an every-down back at this point in his career, but the first-round pick from 2010 is definitely still young enough to produce at some kind of level in the NFL.
Mathews was really solid for the Chargers when he was healthy and on the field in his five seasons. He had two seasons with over 1,000 rushing yards, three seasons with six or more rushing touchdowns and averaged 67.7 yards per game with the Bolts.
Of running backs with at least 32 games played in that five-year period, Mathews ranked 13th in the league in average rushing yards per game. He was also much better in his two healthy seasons, as he averaged 77.9 and 78.4 rushing yards per game in 2011 and 2013, respectively.
He just could not stay on the field and the injuries followed him to Philadelphia as well. Mathews missed three games in 2015 and three games in 2016. In Week 16, Mathews suffered what would be his career-ending injury, a herniated disc.
The Eagles released Mathews the following August and he never played in the league again. He was not even 30. He is now 32.
