2018 Outlook: After spending the first two seasons of his career as DeMarco Murray's caddy, the 6-foot-3, 247-pound Henry is poised for a promotion in 2018. The former second-round pick is expected to be the thunder to Dion Lewis' lightning, which will allow the big man a significant workload on early downs and at the goal line. Henry has yet to eclipse 187 touches in a season, but his efficiency has been terrific. Despite facing an average of 7.1 in-box defenders (third highest) on 286 career carries, Henry sports a 4.31 YPC and 2.25 YAC. The latter is fifth best in the league during that span, and his 2.53 mark in 2017 ranked third. Henry is unlikely to do much as a receiver, so he's more valuable in non-PPR, but his role should allow him fringe RB2 numbers.
2018 Outlook: Lewis -- a fifth-round pick in 2011 -- bounced around the league before bursting onto the NFL scene with New England in 2015. He took his game to a new level last season, finishing as fantasy's No. 13 RB, while setting career highs in carries (180), scrimmage yards (1,110) and offensive touchdowns (nine). Over the past three seasons, Lewis has posted a 4.82 YPC and 2.33 YAC (both are fourth best). Lewis' durability is a major concern, as he has appeared in only 54 of a possible 112 regular-season games during his seven-year career. In Tennessee, the 5-foot-8, 195-pound Lewis will be the lightning to 6-foot-3, 247-pound Derrick Henry's thunder. Both backs figure to play significant roles, with Lewis handling change-of-pace carries and primary passing-game duties. It's enough to allow flex numbers.
