The most interesting period of the Flyers' off-season is less than a week away: Free agency is almost upon us. General manager Paul Holmgren is on a quest to find a No. 1 center, which remains the Flyers' last significant hole to be filled this summer. Will it be Scott Gomez or Daniel Briere? Or maybe even Michael Nylander? Forget Chris Drury: The San Jose Sharks cleared salary-cap space to sign him at the NHL draft in Columbus, Ohio, by trading away two players, Vesa Toskala and Mark Bell.
