Exactly. As important as Elway is to the football operations, Joe Ellis is the one making the business decisions, including whether or not to extend Elway's contract. He and the other two trustees will be tasked with putting one of the Bowlen children in charge of the team, or if one doesn't step up soon enough, be forced by the NFL to sell the team (I hope that doesn't happen).
Elway does nothing to fill the void left by Mr. Bowlen's illness.
