PHILADELPHIA (CBS) – The NFL is the biggest sports in the United States. Dallas Mavericks owner Mark Cuban thinks that might not last much longer.

Cuban, always outspoken, spoke to reporters before the Mavericks’ Sunday night loss to the Brooklyn Nets, and had a lot to say about the NFL’s recent success, expansion, and possible collapse.

“I think the NFL is 10 years away from an implosion,” Cuban said, via ESPN Dallas. “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 number one of business.”

“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 four days a week.

“It’s all football. At some point, the people get sick of it.”

The NFL will have games on four out of seven nights per week during the 2014 season; Sunday, Monday, Thursday and Saturday, with the Thursday night games being simulcast on the NFL Network and CBS.
