Video: Week 8 Flex Rankings & Tiers
J.K. Dobbins maybe just maybe is still the guy here in Denver. Again, not the most likely outcome. And we know he's not going to catch the ball and it's a bad matchup as well. In a closer game against the Chiefs, maybe they lean on the veteran.

Dobbins unlikely lead back; won't catch passes and faces bad matchup.

Dobbins faces significant role uncertainty heading into Week 8. Against Denver, he's not the most likely outcome to lead the backfield; he won't catch the ball and faces a bad matchup, making him a fade for the source. Against the Chiefs in a closer game script, he might see increased veteran usage over Justice Hill, but this scenario-dependent upside is limited. The source is not interested in Dobbins this week.
