2 games into exhibition season, Dolphins have offered only a hint of what offense might be

Two games into the exhibition season, most of the Miami Dolphins' offense remains under wraps.

Receiver Mike Wallace is the team's most heralded newcomer, but while he made his exhibition debut in Friday's victory at Jacksonville, quarterback Ryan Tannehill has yet to look his way with the ball. Lamar Miller, the likely starter at running back, carried only twice for 6 yards, and because of injuries the offensive line has been a patchwork affair since training camp began.

The starters might show a little more Saturday at Houston in the third of five exhibition games. But coach Joe Philbin said the Dolphins will use only half their scheme during the preseason.
