The Facts: GM Steve Keim expressed wide-eyed wonder over Johnson earlier this month, noting that it's "scary" to ponder how good the rookie sensation can be as he develops in his second and third seasons. HC Bruce Arians seems to agree. Asked if Johnson is already one of the NFL's top running backs, Arians replied: "I can't say after one year's work that he is one of the best. But he's got a chance to be one of the all-time best."

Diehards Line: As Chris Wesseling put it, "Arians isn't anointing Johnson a Hall of Famer after 18 NFL games. He's simply pointing out that a well-rounded, three-down back who led the NFL in scrimmage yards from Week 13 through the end of the postseason has a chance to build on that elite production going forward. ..." No doubt. According to NextGen Stats, Johnson recorded the fastest speed by a running back as a ball carrier in 2015. He also launched a 41.5-inch vertical leap at the NFL Scouting Combine last year. He's the rare back who combines freakish physical gifts with natural running and pass-catching ability. And he'll head into 2016 high on the fantasy radar.
