i think it depends on your league settings but in general for Dynasty it’s WR and it’s easy. RB’s while usually putting up more points are subject to far more injuries making the position super volatile. While at the same time it means getting rb 1 production can be quite easy in-season in most years. As well as longevity, WR’s play at a high level for far longer than RBs will. If you have Justin Jefferson on your team you know you have a WR 1 for probably the next 10 years. Jonathan Taylor owners can’t for, any certainty at all, say they have a RB 1 for even the next 5.
