The Miami Dolphins continue to spend money to improve the roster around second-year quarterback Ryan Tannehill.

Just three days after signing dynamic receiver Mike Wallace, the Dolphins signed former New York Jets tight end Dustin Keller Friday to a one-year, $4.5 million contact, according to ESPN.com senior writer John Clayton. This is a nice get for Miami, which simultaneously fills a big need and takes a good player away from the rival Jets.

Keller was Mark Sanchez's safety value in New York for years. Now, Keller has a chance to do the same for Tannehill in Miami. Keller's had two seasons of at least 55 receptions in the past three years.

Keller had a lengthy visit with Miami this week, but left without an agreement. Reportedly, Keller wanted a multi-year contract. But Miami held its ground and Keller eventually took the Dolphins' offer.

Signing Keller short-term is a bargain for Miami. Had Keller not gotten injured last season, he would have received a longer-term contract. He now has a “prove it” contract and can enter free agency again in 2014 with better production and better circumstances. It also allows the Dolphins another year to see if 2012 third-round pick Michael Egnew can develop into a contributor. It’s a win-win situation for Miami.

Meanwhile, the purge in New York continues. The Jets have now lost starters Keller, Pro Bowl safety LaRon Landry, 1,000-yard tailback Shonn Greene, safety Yeremiah Bell and valuable backup defensive lineman Mike DeVito. The Jets have a lot of talent to replace and with very limited resources.
