Shonn Greene, LaRon Landry and Yeremiah Bell joined the growing list of veterans who won’t be a part of the Jets’ rebuilding phase. Greene, coming off back-to-back 1,000-yard seasons, signed a three-year, $10 million contract with the Titans on Wednesday, according to a source. Greene never materialized into the “bell cow” back Rex Ryan envisioned. Landry signed a four-year, $24 million deal with the Colts, with $14 million guaranteed, according to a source, and Bell inked a one-year-deal with the Cardinals, according to a source. Gang Green will have two new starting safeties for the second consecutive season. Tight end Dustin Keller spent Wednesday afternoon visiting and taking a physical for the Dolphins, according to a source. Keller, who missed eight games last season due to injury, stayed in South Florida overnight to continue his visit. The Daily News has learned that the Dolphins hadn’t made Keller an offer as of late Wednesday night, but it appears that he won’t be returning to the Jets. The Jets’ eighth-ranked defense from a year ago is being dismantled. Ryan will have to replace seven defensive starters this offseason.
