The Phoenix Coyotes added much-needed skill at the start of the free-agency period Friday, signing forward Mike Ribeiro to a four-year, $22 million contract. Phoenix also signed free agent goalie Thomas Greiss to serve as a backup to Mike Smith and re-signed unrestricted free agent forward Kyle Chipchura to a multiyear deal. Forward Lauri Korpikoski and defenseman Michael Stone, both restricted free agents, signed multiyear deals as well. Stone re-upped for three years, while Korpikoski's deal is for four, according to a source. Korpikoski's contract is worth $10 million, the source added. Source: ESPN.com
