As Fansided.com noted, Penny, an undrafted free agent in 2016, got to showcase himself a bit towards the end of last season. The 6-foot-22, 234-pound power back carried the ball 31 times for 124 yards and 2 touchdowns. He's a bruising between-the-tackles type who lacks breakaway speed.
The addition of rookie Chase Edmonds, who is quickly establishing himself as the first option behind David Johnson, will relegate Penny to reserve status.
2018 Bottom Line
At this point, it appears multiple injuries to players ahead of him on the depth chart would be necessary for Penny to garner a fantasy-worthy role.
