Robert Griffin III, quarterback
Unlike some veteran free agents on this list, RGIII’s age is not a factor here. The former Heisman winning quarterback is here because of his lack of physical durability.
Try as he might, Griffin, who is only 27 years old, just cannot stay healthy.
His best campaign to date was his 2012 rookie year. He led the Washington Redskins to the playoffs after helping win nine games. That year Griffin passed for 3,200 yards, 20 touchdown and threw only five interceptions. He also added 815 rushing yards and seven touchdowns.
After that star year, Griffin battled one injury after another and was actually benched by Washington the entire 2015 season.
Most recently, the Cleveland Browns released Griffin after a miserable one-year stint. Griffin injured his shoulder in Week 1 in Cleveland and wound up playing in a total of just five games. Only four scores were recorded in that stretch.
Should any team actually reach out to RGIII in free agency, it would have to be out of pure desperation.
