Video: Ranking Every Week 7 Running Back as a Sit or Start
Rhamondre Stevenson is the lead guy... I feel relatively okay about Rhamondre... it's like 12 to 15 touches... Chicago's run defense is dead last... So, I'm going to put Rhamondre in the dub flex category.

Lead back with 12-15 touch projection in a favorable matchup

Rhamondre Stevenson is the lead back for New England, projected for 12-15 touches. While the matchup against Chicago's 32nd-ranked PFF rush defense is favorable, his fantasy output remains uncertain, leading to a 'dub flex' classification.
