Brown was on his way to having a huge year, until he got hurt. But the same line is still there, and Miami has one of the best offensive lines in the league.
When Braylon Edwards went to New York, the Jets' running game got better. Now that the Dolphins have acquired Brandon Marshall, I think he will help the Dolphins' running game, big time.
Teams didn't really have to worry about play action last season, because the Dolphins didn't have a deep threat that they could go to down field.
Now, the Dolphins have the best deep-threat weapon in the entire NFL. Teams will have to pay attention to the pass more, and that will take pressure off the running game.
