From the video

we have one anchor running back, and we have a lot of what-ifs at the running back position. I would stick with the De'Andre Swift and Jefferson side, though. I may be a little concerned with De'Andre Swift with the long-term outlook cuz once you do eventually get in say um Kyle Shanahan guy back into this offense, it's probably going to be a little bit more of a running back by committee and I do think the value of Swift is going to be going down.
STACKED’s take
Anchor RB on 6-0 team; keep over Judkins but watch Shanahan's return.
The source identifies De'Andre Swift as the one anchor running back on a 6-0 team that has scored the most points in the league and allowed the fewest points against them, positioning him as the primary back in a dominant roster. In trade analysis, the source recommends keeping De'Andre Swift over trading him away for Quinshaun Judkins, stating the Swift and Justin Jefferson side is preferable to the Judkins and Amon-Ra St. Brown side. However, the source expresses concern about De'Andre Swift's long-term outlook, noting that once Kyle Shanahan returns to the 49ers offense, it will likely become more of a running back by committee, which will diminish Swift's value going forward.
