Ndamukong Suh signing with Dolphins, per ESPN

The Miami Dolphins will be making the biggest free-agency splash this year.

According to ESPN's Chris Mortensen, the Dolphins are on the verge of signing All-Pro defensive tackle Ndamukong Suh to a massive contract when Tuesday's signing period begins. Suh is easily the best player on the market, and signing him would be a tremendous boost to a Dolphins defense that could become elite with his addition.

Here's an excerpt of Mortenson's report:

The Dolphins and Suh's agent, Jimmy Sexton, discussed those six-year parameters once the 72-hour window opened Saturday for dialogue between teams and unrestricted free agents, sources confirmed.

While Suh's former team, the Detroit Lions, were among other teams making competitive proposals, the Dolphins' parameters far exceeded the rest of the clubs interested in the defensive tackle.

Based off the parameters, Suh also will get $60 million in the first three years on a contract that is expected to average $19 million over the six years of the deal, sources said.

Suh will upgrade a Dolphins defense that finished 24th in total rushing yards allowed per game last season, and could be on the verge of losing defensive tackle Jared Odrick. There's also the possibility the team cuts Randy Starks, so Miami's defensive line could be getting a massive overhaul and upgrade at the same time if Suh does in fact sign with them.
