His heirs have no interest in taking over?Allen's death is going to have a major effect on the team. The Seahawks had a very shaky history of previous ownership before Allen purchased the team. At one point, they were almost headed to LA. The whole city of Seattle has had ownership issues with all of the teams throughout the years, and I don't see it getting better with the Sonics leaving, and the Mariners not exactly a model of stability. Allen knew well enough to hire good people and stay the hell out of the way of their decisions. Are they going to be able to find someone to buy the team at the price it's going to require? It will likely require multiple partners forming a group to buy the team. And what kind of philosophy are they going to have in regards to running the team? This almost certainly means the end of the Pete Carroll era and likely the John Schneider era as well (he probably heads back to Green Bay).
The future is really, really murky now and who knows what happens going forward.
