But not to worry.
Yesterday, in an email to the Daily News, Cuban said it might all work out.
"You won't remember this season if you get a superstar in the draft," Cuban wrote. "And [Sixers] fans will be thrilled."
Switching gears, what Cuban isn't thrilled about is the NFL.
On Sunday night, before the Mavericks' overtime loss to the Nets, Cuban addressed a group of reporters about the NFL's plan to play more games on weekdays.
"They're trying to take over every night of TV," Cuban said. "Initially, it'll be, 'Yeah, they're the biggest-rating thing that there is.' OK, Thursday, that's great, regardless of whether it impacts [the NBA] during that period when we cross over. Then if it gets Saturday, now you're impacting colleges. Now it's on 4 days a week. It's all football. At some point, the people get sick of it.
"I think the NFL is 10 years away from an implosion. I'm just telling you, pigs get fat, hogs get slaughtered. And they're getting hoggy. Just watch. Pigs get fat, hogs get slaughtered. When you try to take it too far, people turn the other way.
"I'm just telling you, when you've got a good thing and you get greedy, it always, always, always, always, always turns on you. That's rule No. 1 of business."
