Fantasy Upside
Jaylen Samuels didn't play much early in the season for the Steelers, but was given a larger role late in the year when James Conner was injured. Samuels posted 328 total yards and a touchdown in his three starts with Conner out. He's an excellent receiver out of the backfield, having caught 26 of his 29 targets in 2018 for 199 yards and three touchdowns. That role could expand in 2019.
Fantasy Downside
The addition of rookie Benny Snell means Samuels' role will probably be limited to being a third-down back, even if Conner is injured. He'll have more value in PPR leagues than he does in straight yardage or scoring leagues.
2019 Bottom Line
Samuels is excellent catching the ball out of the backfield and his size makes him a threat to score down close, as his three touchdowns on 26 catches last season shows. But he's limited as a runner. His 100-yard rushing game against the Patriots last season was the first of his career -- at any level, including high school.
