Previewing Dolphins' new-look offense

In one week, the Miami Dolphins went from one of the least threatening passing offenses in the NFL to one of the league’s deepest and most formidable.

The Dolphins spent a lot of resources at receiver and tight end in free agency. They signed receivers Mike Wallace, Brandon Gibson and tight end Dustin Keller to boost their air attack.

Miami’s receivers were last in the NFL with three touchdowns in 2012. Wallace and Gibson combined for 13 touchdowns last season and will bring those talents to Miami. Keller also added two touchdowns at tight end. Second-year quarterback Ryan Tannehill has to be smiling this week.

Dolphins general manager Jeff Ireland said he would get Tannehill upgrades at the skill positions and he delivered. Perhaps the only unknown is the future of receiver Davone Bess.

Gibson signed a three-year contract, but Bess is the only true slot receiver on the roster. If Bess isn’t traded or released, either Bess or Gibson will get little playing time as a fourth receiver next season.

But this is a good problem to have. Last year, Miami had too few receivers. This year, the Dolphins have too many.
