De'Von Achane leads backfield scoring in return -- but doesn't take over backfield

The final numbers from Sunday's blowout win over the Commanders suggest Dolphins RB De'Von Achane took over the backfield in his second return from a knee injury. The rookie tallied a 17-73-2 rushing line, leading the team in carries, yards, and TDs. And he ranked third among Dolphins in receptions (3) and receiving yards (30). Raheem Mostert trailed at 11-43-1 rushing, catching his lone target for 8 yards. But usage looked very different before and after halftime. According to Pro Football Focus, Mostert played 19 of Miami's 29 offensive snaps in the first half, compared with Achane's 12. Mostert hit halftime with a 9-3 carry lead and 1 target to Achane's 2 -- and Miami leading 31-7. Mostert played just 4 more snaps after the break, compared with Achane's 23. The rookie scored both of his TDs in that span. Mostert's TD came in the first half. So what's the takeaway? Expect both RBs to remain plenty involved and carry weekly TD upside. The remaining four matchups in most fantasy schedules don't look good for RB scoring (10th-worst schedule in the league by our adjusted fantasy points allowed). But the slate looks even worse for passing points. So consider Mostert and Achane weekly starting options the rest of the way. Jeff Wilson Jr., meanwhile, garnered only 4 carries even in a blowout victory. He's safe to drop in most fantasy formats.
