The Seahawks re-signed their most important 2007 free agent Tuesday when they reached a two-year contract extension for coach Mike Holmgren, whose contract was set to expire after this season. Holmgren's agent, Bob LaMonte, finalized the contract extension one week after flying to Seattle last Tuesday to meet with Seahawks officials. Terms of the contract weren't available, but Holmgren was negotiating from a position of strength. With a $7 million salary in 2006, Holmgren was negotiating as the highest paid coach in the league.
