Bloomberg Business News is reporting that Bain Capital Partners LLC (a reputable Boston investment firm) has increased its offer to buy the NHL to more than $4 billion. Their previous offer was for as much as $3.5 billion at the governors’ meeting in March, as reported on On the Wings. As in the previous offer, the proposal would have all 30 teams run out of a central office. This league structure is currently in place in the WNBA and MLS, and was in the defunct XFL.
