"Offense has been the variable in the Miami Dolphins' experiment the past three seasons.

With a new coach, the players once again have to adjust to another system. After yearly change under former coach Tony Sparano, the Dolphins now turn to Joe Philbin and the highly-successful West Coast offense.

"I'm not even sure what the West Coast offense means," Philbin said Thursday. "I do know we're going to be sound, we're going to protect the A and B gaps when we send the quarterback away from the center."

The West Coast offense is an expected upgrade after the Dolphins struggled the past three seasons under Sparano. Those teams experimented with a variety of offenses, including the invention of The Wildcat and some pro set under offensive coordinators Dan Henning and Brian Daboll."
