Cuban tells a group of reporters at the NBA's summer league in Las Vegas that he intends to ask the league's Board of Governors to inquire about the situation.
According to a story posted on the Cleveland Plain Dealer's website Sunday, Cuban says the league needs to develop more definitive rules governing the issue of player tampering.
"I'm going to bring it up to the league that we really do have to re-evaluate the issue of player tampering," Cuban told the newspaper. "Who knows what will happen? But I have to suggest it to them because there has to be more definitive rules."
It's not just the Cavs," he added. "It could be any team. It could be the Heat in a couple years. I'm not saying it's going to be easy. But there has to be a way to keep these guys away from each other for the last week anyway."
NBA owners are scheduled to meet Monday in Las Vegas.
