DALLAS -- Mavericks owner Mark Cuban is firing criticism at a league office again, but this time he has the NFL in his crosshairs.
"I know we're just little pissants compared to the NFL, but seriously, the NFL is turning into the ugly American when it comes to sports leagues," Cuban said. "They don't give a crap about anybody but themselves."
Cuban continued his rant via Twitter on Wednesday, pointing out a second NFL game going head-to-head with an NBA game in Boston.
Tweeted Cuban: "NFL couldnt schedule the Pats for late game on Sun rather than opposite Celtics @1pm?"
The Boston Celtics host the Toronto Raptors at 1 p.m. ET, while the New England Patriots open the playoffs at home against the Baltimore Ravens at the same time.
NFL spokesman Greg Aiello has declined to respond to Cuban's comments.
The Mavericks' sellout streak of 334 consecutive games is not in jeopardy Saturday night because all the tickets have already been sold, Cuban said. However, he anticipates a high number of no-shows.
Cuban had nothing but praise for Cowboys owner Jerry Jones, his partner in bringing the NBA All-Star Game to Cowboys Stadium in February. However, Cuban lashed out at the NFL, which he said could lose the political support of other professional sports leagues if it continues to be inconsiderate with its scheduling.
"There's a balance between all the leagues," Cuban said. "They deal with similar issues. They deal with issues with copyright, antitrust, [Federal Communications Commission], all kinds of things. And it's going to bite them in the ass one day."
Cuban concluded with a jab at the NFL.
"Maybe the other leagues, when it comes to supporting them, will pull a Jim Irsay and disappear in the middle of the night," Cuban said, referring to the Colts' move from Baltimore to Indianapolis that was actually orchestrated by Jim Irsay's father Bob in 1984.
