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

4. Eli Manning - 39,755

Eli Manning, like Philip Rivers who he was traded for, is also entering the final year of his contract, putting teams on alert for a crazy quarterback roundabout in the 2016 off-season. He'll be mocked for his turnovers, but Manning's two Super Bowl rings and his inevitable 40,000+ passing yards will form his defence after he's done with the sport. With Odell Beckham Jr. expected to shine again, Manning will be re-invigorated this term, so expect the best from him once again.
