RapSheet mentions the Ravens and Colts as two of the teams interested in the 28-year-old. They're waiting for the "frenzy to die down" before making a run at Mack, who was slapped with the transition tag by the Browns. Indianapolis needs a center after releasing Samson Satele, while Baltimore needs an upgrade on Gino Gradkowski. Mack is arguably the best center in the NFL.
Dolphins re-signed DT Randy Starks to a two-year, $12 million contract.

The Dolphins moved quickly on keeping Starks after losing Paul Soliai to the Falcons. A starter for the Dolphins since 2009, Starks remained both an effective run stopper and pass rusher last season. Although he's now 31, Starks has been highly durable. He hasn't missed a game since 2007.
