The below part was posted on another Bears forum by a user today. He was quoting some article I believe.
Not sure how accurate or up to date it is ... so grain of salt.
But here’s the wrinkle: The NFL bylaws state that a single lineal family must control 30% of each franchise (which Virginia does via the voting trust). However, when she dies, the voting trust expires and the Bears ownership “will be thinly spread over more than a dozen Halas heirs, without a single person or descendant anywhere close to that 30% threshold.”
In the end, it seems very likely that when Virginia passes, the team will be required to consolidate control of at least 30% of the team into a “single wing” of the McCaskey family, potentially including the sale of some equity to outsiders.
And that could cause a ton of friction (lawsuits, exits, desires to sell, etc.) if not handled delicately. Traditionally, those issues tend not to pop up until the rubber meets the road (a.k.a. Virginia passes). Everyone will play nice until then, not to rock the boat, but if anyone feels slighted by the direction of the $5 billion company, well … there’s a whole HBO series about it."
