Maxwell, who punched a fan in 1995 for heckling during a game in Portland against the Trail Blazers, tweeted that if Irving felt slighted he should do something about it and gave perspective from his own incident during his career.
“It’s just a bottled water right? If you feel disrespected then do something about it or it will keep on happening. Guess how many times a fan made a comment about my stillborn daughter? It cost me some money & a suspension but I sleep fine every night knowing I stood up for her,” he tweeted.
There was an uptick over the last few days in incidents between fans and players.
Five fans received indefinite bans from arenas for incidents with players.
“The return of NBA fans to our arenas has brought great excitement and energy to the start of the playoffs, but it is critical that we all show respect for players, officials and fellow fans,” the league said in a statement. “An enhanced code of conduct will be vigorously enforced in order to ensure a safe and respectful environment.”
