NFL: Top 15 All-Time Passing Yard Leaders Still Playing

6. Philip Rivers - 36,655

This could well be Philip Rivers last season with the Chargers, or at least, in San Diego. Rivers has thrown for an impressive total over 11 years, and has playing in every regular season Chargers game since the start of 2006. However, the 33-year-old's six-year $91,800,000 contract is up at the end of the season, but if the Chargers plough ahead with a potential relocation to Los Angeles, Rivers has stated that he won't be going with them and will instead try his luck on the free agency, a potentially game-changing move for a franchise.
