Monty Williams, the coach of the Phoenix Suns, said that the NBA should consider having a section for the families of visiting teams in the stands.

The Dallas Mavericks and the Phoenix Suns were playing in the Western Conference semifinals. According to sources, several family members of Paul were harassed by a fan in the crowd.

Following the Mavericks' win that tied the series at 2-2, Paul addressed the disturbing Mother's Day incident on social media.

He said that players were fine for saying stuff to the fans, but the fans could put them in the hands of their families.

Robin and her two children watched the game in close proximity to the Suns bench at American Airlines Center, according to sources. According to a source familiar with the situation, Paul's mother put her hands on his wife and his kids were there to witness it. A different source said that Paul's wife was followed up the aisle when she left her seat.

A source familiar with the situation said that they felt very unsafe.

It is a hard one, because it is happening more and more, Williams said Monday at Suns practice. Something has to be done, whether or not we have to give these people a section or a suite.

We have to do what we need to do before it gets to a level. Yesterday was not necessary.

The Mavericks said after the game that they were aware of the incident between a fan and Paul's family. The game was still being played, so Williams didn't know the extent of the harassment in real time.

The Mavericks and American Airlines Center quickly removed the fan from the game.

The investigation into the incident involving the Paul family was concluded by the Mavericks and American Airlines Center. The fans were quickly ejected from the game after they tried to hug the Paul family on the concourse. The fans who were involved in the incident will not be allowed to return to the arena for at least five years.

After Monday's practice, Paul didn't speak to the media.

During the NBA Finals in Milwaukee last season, Johnson's girlfriend was hit in the back of the head and had beer spilled on her. Johnson said he did not hear about the incident until after the game.

It was a big scene for Johnson.

The fan was kicked out of the game after security in Milwaukee handled the situation. He said security can't keep families safe all the time.

The fans have to be part of the responsibility. There is no other way around it. You have to address the problem with the real problem. It's not possible for a fan to go up to someone's mother and harass them.

The series is tied 2-2 and Game 5 is Tuesday in Phoenix.

Williams said that the fans in Dallas are cheering for their team. I have never had this kind of incident at that arena, even going back to the old spot.
