Video: 5 Sleeper RBs You NEED to Draft
He's a match up issue for every defense. I think he has a lot of pass game value that he hasn't been able to really represent in his career, but it's showing so far in camp.

Undervalued sleeper with elite efficiency and pass-game upside

Ian Hartitz highlights Keaton Mitchell as a premier sleeper RB (RB57, pick 132.9) who is currently being disregarded. Despite being an undersized speed back, Mitchell has shown elite efficiency with a 6.3 career yards-per-carry average and is demonstrating increased pass-game value in training camp. Hartitz views him as a matchup issue for defenses and a viable RB2 option for hero-RB builds who can provide 8-10 touches per week.
