Video: Ranking Every Week 15 Running Back as a Start or Sit
Gent is going to fall down pretty dramatically. He's definitely not a mustar. don't feel good about him just based on the lack of push, but he's typically very involved in the passing game. So, I'm going to throw him into the dub flex category.

Jacobs dub flex vs. Denver; goal-line work provides floor despite OL issues

Josh Jacobs falls dramatically in rankings for Week 15 vs. Denver due to the Raiders' offensive line struggles; he is not a must-start despite typical passing-game involvement. Classified as dub flex due to lack of push from the OL and uncertainty around Jaylen Carter's return. However, Rashad White ranks Jacobs in the feels-good category for Week 15 vs. Denver; despite low ground efficiency due to Green Bay's weak offensive line, Jacobs monopolizes goal-line work and Jordan Love sustains drives long enough for Jacobs to accumulate sufficient yardage.
