Mostert’s absence last week resulted in 19 opportunities for Achane against the Ravens, which he was able to turn into 137 yards from scrimmage and a touchdown in a game that was well out of hand relatively early into the contest. With Mostert potentially missing Week 18 while the Dolphins gear up for a playoff run, Achane has plenty of intrigue heading into the matchup against the Bills. In the previous matchup this season between Miami and Buffalo in Week 4, Achane handled eight carries for 101 yards and two touchdowns, finishing as the RB5 on the week in Buffalo. This week’s game is in Miami, and Achane’s upside as an RB1 will be contingent on Mostert missing his second game in a row with knee and ankle injuries. Fantasy managers should pay close attention to practice reports later today to get the best idea of what to expect heading into the first Sunday of 2024.
