The Seattle Seahawks will not ask Tarvaris Jackson to replace what Matt Hasselbeck has represented for the past 10 seasons. That wouldn't be very logical. If the Seahawks are smart, they'll ask Jackson to compete with Charlie Whitehurst (and others) as the organization searches for its next long-term starter behind center. And that will be the point: searching for the next quarterback. Jackson, who reached agreement with the Seahawks on a contract that cannot be signed before Friday under league rules, may or may not succeed in the role. He's one option for a team that remains early in the process. Seattle could still draft or otherwise acquire its future quarterback in 2012, making Jackson only one part of this story. The bottom line, of course, is that Hasselbeck should have finished his career in Seattle. I think he would have finished his career in Seattle if Mike Holmgren, the man responsible for acquiring Hasselbeck in 2001, had remained in a leadership position with the team. Holmgren is long gone, however, and the current leadership team is doing what Holmgren sought to do when he arrived in Seattle back in 1999: move on with an eye toward the horizon. Back then, Holmgren turned his back on an aging Warren Moon even though Moon had tossed 36 touchdown passes with 24 interceptions while starting 24 of the 25 games he played in Dennis Erickson's final two seasons as head coach. Moon was 42 years old at the time and would start only one more regular-season game, with Kansas City.
