32-year old RB Ricky Williams has really stepped up after Ronnie Brown was injured.  Williams has carried the ball 115 times for 519 yards (4.5 ypc) with 4 TD runs in his last five games.  He has also caught 8 passes for 37 yards (4.6 avg) with a TD grab in his last five games.  Williams’ running has kept the offense afloat after the injury to Ronnie Brown that many thought would dismantle the offense.  Williams has now played in 13 games this season for the Dolphins and he has carried the ball 200 times for 975 yards (4.9 ypc) with 10 TD runs.  He has also caught 24 passes for 225 yards (9.4 avg) with 2 TD grabs.  The Dolphins need Williams to keep playing well if they are going to make the playoffs this season.
