It's been more about their quarterback play, and Ryan Tannehill has arguably been the second-best sophomore quarterback behind Seattle Seahawks Russell Wilson. He's averaged 298 passing yards over his last four, but there really hasn't been much of a running game through the season. The Dolphins ranking in the bottom 10 in rushing yards, and more than 200 of those rushing yards have come from Tannehill.
Last week, running back Lamar Miller carried the ball a team-high 15 times for 61 yards and seems to have regained most of the work after Daniel Thomas got hot with a 105-yard game against the Pittsburgh Steelers in Week 14.
The Dolphins will take on the Buffalo Bills in Week 16, but it looks like they'll use a predominantly pass-happy approach based on the weak secondary of the Bills.
Fantasy impact: It's just too risky to go with Miller or Thomas. The don't offer enough upside, and this situation has been a mess all year.
