The Colts have done much better the last two weeks on the ground, and they need to keep doing that. If you look at the games they've won, they rushed for near or over 100 yards in all of them. In the games they lost, they failed to get ground game going.
Sunday will be another test, as the Dolphins are the third-best team in the league against the rush. They only give up 82 yards per game on the ground. Compare that to the Colts averaging 107.1 yards per game on the ground.
The Colts need to get at least to their average, if not better, if they want to win.
The Dolphins have such a good rush defense that they can afford to send all-out pass blitzes at the quarterback. They have 22 sacks on the year and have eight interceptions. Cameron Wade has 7.5 sacks just by himself, so the Colts need to counter that with a solid run game.
It's been no secret that the Colts offensive line has struggled to protect Andrew Luck. If it weren't for Luck's ability to get out of the pocket and extend plays, they could be winless right now. They struggled last Sunday to keep Luck off his back, but where they helped him is finding out ways to build holes for the run game.
The Colts figured that out and did nearly all play-action passes in the second half of the Titans game, having great success doing so. The rush kept the defense honest and allowed Luck a bit more time to hit open guys.
The Colts have to do this on Sunday. I can't put enough importance on that.
The Dolphins are going to bring pressure and are going to be ball-hawking. If Indianapolis can get a solid running game going, it will negate that and give the Colts enough time to score points.
The game will be decided on the Colts' rushing total. If they're below 100 team yards, they will likely lose.
