39. Christian McCaffrey

Jeremy Brevard-USA TODAY Sports

Six years into his promising career, Christian McCaffrey has already blossomed into one of the most dangerous players the NFL has ever seen. In Year 2, the Stanford great rushed for 1,098 yards and hauled in 107 passes for 867 additional yards. In 2019, McCaffrey exploded for 1,387 rushing yards, 15 rushing touchdowns, and hauled in 116 passes for 1,005 yards and four scores. Only 26, McCaffrey has plenty of time to improve his legacy. The only thing that will hold CMC back from moving up this list is bad luck.
