As first reported by Adam Shefter of the NFL Network, the Seattle Seahawks have released defensive end Grant Wistrom. This is yet another step in the teams constant process of reinventing its defensive line. It is also a somewhat expected move, as team president Tim Ruskell had said that after Seattle recently signed former Atlanta Falcons DE Patrick Kerney to a six-year, $39.5 million deal, Wistrom would be asked to restructure his own contract, which was six years and $33 million, signed in March of 2004. It would now seem that Wistrom and his agent, Tom Condon, refused to restructure. Condon is also Steve Hutchinsons agent, and was the pointman in the poison-pill offer sheet that allowed the Minnesota Vikings to steal the Pro Bowl guard away from the Seahawks in 2006. It was not a contract that Wistrom had lived up to he was brought in to bring change to Seattles defensive line, but he never totaled over 52 tackles and four sacks in a season. The Seahawks will save $3.5 million in cap room in 2007 by releasing Wistrom, but they cant use the money until June 2, pursuant to the leagues Collective Bargaining Agreement. Wistrom was selected out of Nebraska as the sixth overall pick in the 1998 draft by the St. Louis Rams. Stay tuned to Seahawks.NET for more free agency news as it becomes available.
