I think it will wind up a little higher than that even. The max it can get to is around $123.5 million, as the league and players agreed to an increase of no more than 10% in exchange for not lowering in the 2020-2021 season when revenue was hammered by Covid. With the amount of parity in the East and amongst the top 4 in the West, I think there will be a lot of long series in the playoffs that will bring in extra revenue still.
Any cap/tax increase is generally good news for the C’s. Free agency salaries rise with cap increases, because minimum, mid-level, and max salaries are all pegged to the cap, as do the salaries of draft picks. As the C’s have 9 players with guaranteed contracts, one players non-guaranteed (Horford) and one player potentially offered a qualifying offer (Bol Bol), they have 9-11 players with salaries that won’t be affected by this increase, meaning most of the increase just adds flexibility to the C’s books, particularly with regard to staying under the hard cap if they look to use a TPE to acquire a second-tier free agent.
