The Miami Dolphins have added yet another piece to the puzzle.
Landing Keller accomplishes two tasks for the Dolphins. First, it gives young quarterback Ryan Tannehill a legitimate pass-catching target underneath to replace the departed Anthony Fasano, who agreed to a four-year deal with the Kansas City Chiefs.
Second, it sinks a knife deep into the heart of the division-rival New York Jets, who couldn't afford to keep Keller and have now lost arguably their most consistent player on offense.
It was thought Keller might pass on the Dolphins' one-year offer. General manager Jeff Ireland has thrown bundles of money at players who haven't proved they can help the Dolphins win, but the Keller deal is cunning on the surface. He was sidetracked for most of last season by hamstring injuries and the short contract now allows Miami to decide if it wants Keller around long term.
He made just five starts last season for the Jets, but Keller was outstanding in 2011, accounting for 65 receptions, 815 yards and five touchdowns. He's a solid fit for the Dolphins' West Coast-style passing attack.
If Keller can be counted on for 16 games, Miami has spun magic here. Keller's blocking could use help, but this is another bold move by a Dolphins team looking to win now.
For the Jets -- who thought enough of Keller to make him their first-round draft pick in 2008 -- it's another ugly moment in an offseason determined to suck the life out of Florham Park.
