If this sale does go down and ends up being as monumental as expected it could be massive for the hockey world. The Tampa Bay Lightning 10 years ago were not one of the most valuable franchises in the NHL. However, one dynasty and several Stanley Cups later, and now they are the highest-priced team in the league.
This sale could incentivize owners to try and compete and spend to the salary cap in pursuit of a similar return in the future. Of course, many owners do not plan to sell their franchises but it could be a good incentive for some owners who in the past had none to invest in their teams.
