Dolphins agreed to terms with TE Dustin Keller, formerly of the Jets, on a one-year contract. The Jets' latest defector will remain in the AFC East. The sides had been near an agreement for 48 hours, but Keller was holding out for a multi-year deal. He didn't get it, and now founds himself a part of a brazenly "all in" squad for 2013. Keller represents a major upgrade for a team that's had trouble getting the tight end position right in recent seasons, but is coming off a down campaign. Thanks to injuries and Mark Sanchez, Keller was limited to 28 catches for 317 yards and two touchdowns in eight games in 2012. A chain mover and a red-zone threat when healthy, Keller should find himself on the TE1 radar with Ryan Tannehill.
