Outspoken Dallas Mavericks owner Mark Cuban is predicting the NFL's decline.
Cuban says the league will see a drastic drop in popularity over the next decade due to its greed when it comes to television deals. He says it's poor business to play games on days other than Sunday and Monday.
The NFL recently announced an expanded deal with CBS to broadcast Thursday Night Football.
The NFL Network will also broadcast a Saturday doubleheader in Week 16 of the upcoming season.
Cuban says the NFL is making a mistake by valuing the television money over the convenience of fans who are used to planning to watch their team on Sunday or the occasional Monday night.
