This has been expected. The rumors are the NBA is trying to come up with a plan to slowly raise the cap now so the NBA players still get the proper % of the revenue when the big money hits without a sudden cap spike.
They'll have to negotiate with the players to alter the escrow account then, since if the cap is raised to account for 50% of the extra TV money, with the other 50% coming the following year when the TV deal takes effect, for certain the players will make more than the 51% of revenue they're allowed to.
For perspective, if the NBA made $2.67 billion in TV revenues instead of $930 million in TV revenues this season (which assumes that the NBA gets the average annual value of the respective TV deals instead of graduated payments) the salary cap this year would have been about $89 million instead of $63 million, assuming my quick math is near correct.
If they don't end up raising the cap by anything other than the normal amount, it will be interesting to see what players who have player options and ETO's in their contracts do. A player like Kevin Love stands to get a decent increase next season, but could get a huge one the following year. Even Jeff Green, while he isn't sniffing max money, would be a free agent in a bigger pool of money and could expect a salary bump, so maybe waiting an extra year works for him.
Finally, because everything Celticsblog must include Rondo -- if the big jump doesn't occur for two years, Rondo would be a bargain if he got a max next year. A max contract next year would start somewhere in the $18-$19 million range. In 2 years, Rondo would instead be eligible for a contract starting in the $29-30 million range (partly due to an extra year of experience -- if we hold that will part constant, he'd be eligible for a contract in the $25-26 million range -- still a huge jump). It will be tricky for the Celtics if they do escalate the cap somewhat, as then Rondo might be eligible for a contract which, for a year, would make him the highest paid player in the game (along with Aldridge, who would certainly get the same deal, and Love, if he opts out.) The following year a ton of players would pass him.
