Miami Dolphins
Lamar Miller (Running Back): This Dallas defense has done nothing for the past few games and facing one of the hottest running backs should not bode well for them unless the addition of Romo flips the time of possession. Romo converting third downs and throwing the ball deep will take a lot of time off the clock so Miller's opportunities could be limited and Miami could see themselves trailing. Dallas has given up the 4th most points to running backs though so there is a possibility he can go off.
Jarvis Landry/Rishard Matthews (Wide Receiver): Landry and Matthews are going up against a defense that has given up the 5th fewest fantasy points to wide receivers all season long. Landry has accumulated 25 targets over the past two games and Matthews will likely see lighter coverage but Landry is more of a playmaker. It is a bad matchup but I would start either of this guys as a flex or a low tier WR2.
Dallas Cowboys
Tony Romo (Quarterback): Romo is returning to the field for the first time since week 2. With Dez Bryant healthy and this offense ready to explode expect number 9 to have an extra special performance against the Dolphins.
Dez Bryant (Wide Receivers): With Romo Back Dez should be back to normal as one of the premier passers in the game is finally under center for the Cowboys. Bryant is a top tier wide receiving option this week and going forward. The Cowboys will need a lot of touchdowns if they want to win out and attempt to make the playoffs, the majority of those touchdowns should come from Dez Bryant.
Darren McFadden (Running Backs): McFadden will face a scary looking defense on paper however McFadden should be able to find some room. It is safe to say with Romo back defenses will once again fear this passing game so McFadden should put together a nice game against a team that has given up the 2nd most fantasy points to running backs this season.
Jason Witten (Tight End): The return of Romo spells production for Romo's biggest security blanket. Witten should see his targets increase as well as his red zone targets so he should be a sneaky TE 1 play for this week.
