Right after the Flyers made their final pick in last Sunday’s NHL Entry Draft, general manager Paul Holmgren walked from his team’s ice-level table at Newark’s Prudential Center to the Los Angeles Kings’ table and tapped GM Dean Lombardi on the shoulder. Lombardi looked back at Holmgren, then immediately left his post to have a one-on-one talk that lasted more than 10 minutes. Old friends who worked together with the Flyers, Holmgren and Lombardi could have been just catching up. Or perhaps Holmgren was talking trade to dump a contract that would create added cap space for today, the start of the league’s free-agent signing period. “It’s going to be crazy,” Holmgren said recently. “So we’ll see what happens. We know we have needs and we’re in the middle of trying to work out how we can fill those needs.” The most pressing need is adding a goaltender to replace Ilya Bryzgalov and share duties with Steve Mason, and the latest reports had the Flyers looking to sign Ray Emery or Evgeni Nabakov but not 39-year-old former Vezina Trophy and Stanley Cup winner Tim Thomas. The Flyers already have had a busy offseason that continued Thursday with captain Claude Giroux agreeing to an eight-year, $66.2 million contract extension and veteran forward Adam Hall returning on a one-year, $600,000 deal. Previously, the Flyers added a star center last week by signing Tampa Bay-buyout Vinny Lecavalier (5 years, $22.5 million) and improved their defense by adding Mark Streit (4 years, $21 million) in a trade-and-sign, and they also freed up cap space by buying out Bryzgalov and center Danny Briere. The Flyers also made a minor move Thursday signing a one-year, $600,000 deal with veteran forward Adam Hall, whom they acquired late last season off waivers.
