The Panthers were extremely active when the NHL's free agency period opened Friday afternoon, signing four players by 2 p.m. Florida replaced free agent goalie Tomas Vokoun with Jose Theodore; signed veterans Scottie Upshall and Ed Jovanovski to four-year deals; and signed former Nashville winger Marcel Goc to a three-year deal. Jovanovski was selected by the Panthers with the top pick of the 1994 draft and stayed with Florida until being sent to Vancouver part of the Pavel Bure trade in 1999. He has spent the past five seasons with the Coyotes. Jovanovski's first NHL contract came with the Panthers and this will likely be his last. He will be 35 when the 2011-12 season begins. He'll get $16.5 million over the course of the deal. Upshall, 27, made his NHL debut on Oct. 15, 2002, and has played for Nashville, Philadelphia, Phoenix and Columbus. He had 22 goals with the Coyotes and Blue Jackets last season. In 361 NHL games, he has 86 goals with 86 assists.
