THREE THINGS THAT NEED TO GO RIGHT ...
Dominate with the running game. The Dolphins have been susceptible against the run, allowing more than 120 yards on the ground in four of their past eight games. Suddenly-disgruntled Willis McGahee has averaged 94.4 rushing yards for the Ravens in five games in his hometown of Miami.
Cage up "The Wildcat." The Ravens were the first team to solve Miami's gimmick offense. The Dolphins' Wildcat offense - which is a direct snap to running back Ronnie Brown - produced 4 yards on five plays.
... AND THREE THINGS THAT COULD GO WRONG
The Dolphins protect the ball. Miami equaled the NFL single-season record for fewest turnovers (13). The Ravens are 3-3 when they fail to force multiple turnovers.
Joey Porter wreaks havoc. The Dolphins' trash-talking outside linebacker recorded two of his 17 1/2 sacks this season against the Ravens. Before that game, Porter had one sack in his previous 12 meetings with the Ravens.
Joe Flacco plays as if it's his first postseason game. The Ravens' rookie quarterback has played big in big games. And this isn't the time to start making costly mistakes against a Miami defense that has six interceptions in its past two games.
