Dolphins running back Raheem Mostert scored 21 touchdowns last season and he was the team's starter in the first week of this season, but his playing time has dropped sharply over the last few weeks.
Mostert played 30 offensive snaps in Week Eight, but has played just 32 over the last three weeks as De'Von Achane has taken on the clear lead role in the backfield. Mostert is not the only Dolphins veteran to see their role diminish — linebacker David Long was released after starting six of the first eight games of the season for example — which led to a question for head coach Mike McDaniel on Wednesday about whether he's trying to send a message to players.
