Speaking as the only major professional sports team owner in Dallas who has won a title in the current millennium, Mavericks owner Mark Cuban warned Cowboys owner Jerry Jones against making a rash decision.

The Fort Worth Star-Telegram reported Friday that Cuban talked about the Cowboys situation before the Mavericks played host to the San Antonio Spurs the night before.

"I think Jerry would be quite crazy to fire Jason Garrett, not that he would," Cuban said. "If you're going to fire a coach you better have something really good to go to before you even think about making a change."

The Cowboys enter Sunday's regular-season finale at Cowboy Stadium with what amounts to a playoff game with the Philadelphia Eagles. Dallas, who will be without quarterback Tony Romo, will miss the playoffs for the third consecutive year with a loss on Sunday.

Garrett's record during his three full years would be 24-24 with back-to-back-to-back 8-8 seasons unless the Cowboys can stop the Eagles.

But even in that scenario, Cuban says Jones should retain Garrett unless the players don't believe in him.

"Unless there's something really fundamentally wrong in the way they play, it's probably not the coach," Cuban said.

Cuban added that whatever decision Jones does make about Garrett should not be media-influenced.

"The last thing you care about is how the media responds," Cuban said. "Maybe you come out after the fact and explain your logic so everybody understands.

"He has his radio show, TV show, whatever, and he has a chance to do it there and he knows that, so what's the rush? And knowing Jerry from a business perspective, he knows if he waits and says he's going to explain it on one of those shows, the ratings will be much higher."
