Keller, 28, was initially holding out for a multi-year deal, but Miami was willing to cave, and the market just wasn't that hot for him. Injuries derailed his 2012 season, as he only appeared in eight games, catching 28 passes for 317 yards and two touchdowns.
Keller was drafted by the New York Jets in the first round in 2008. Over five seasons, he hauled in 241 receptions for 2,876 yards and 17 touchdowns. His best year came in 2011, when he had 65 receptions, 815 yards and five scores.
Keller's poor blocking skills make him somewhat one-dimensional in the offense, and the injury concerns remain, but when healthy, he's a quality possession receiver and red zone threat. At the very least, he's a big upgrade for the Dolphins and won't have Mark Sanchez throwing to him anymore. A comeback season is not out of the question, if he can stay healthy. This is a solid low-risk move by Miami, who have been spending money like a drunken sailor up until now.
