49ers RB Jordan Mason “appears” to be the favorite for the RB3 role, per beat writer Jack Hammer. Mason's main competition is 2022 Round 3 pick Tyrion Davis-Price. “The second-year back is a more fluid runner and does a better job of setting up his blockers than Ty Davis-Price,” Hammer writes. “He has also looked much better in pass protection, squaring up defenders consistently.” We’ll see what the rest of the preseason brings. But the RB3 role in San Francisco figures to have some fantasy relevance this season — especially with No. 2 Elijah Mitchell already battling an adductor injury.
