There is no need for the Jacobs family to show their hand at this point. Maybe he gets involved if the team is in danger of leaving. All it mentioned was that he would not sell the Bruins to purchase the Bills. Well that is not going to be a problem if their family wants to own both teams.
Stan kronke owns the St. Louis Rams, Denver Nuggets, and Colorado Avalanche franchises. Jeremy Jacobs can give up control of the Bruins to one of his sons and buy the Bills. The other option would be for someone else in his family to purchase the team as long as they are not part of the Bruins ownership.
I think the Jacobs family is still in play here despite everything.
