WASHINGTON -- John Wall has already made enough money during his basketball career to last a lifetime and his new supermax contract worth $170 million is just kicking in. When he is done playing in the NBA, he doesn't have to do anything at all if he doesn't want to.

But there is at least a small part of Wall that believes coaching could be in his future. He loves the game enough to not rule out the possibility.

This year will give him a taste of what being a coach is all about. While he rehabs his ruptured left Achilles, he will serve as an unofficial assistant to head coach Scott Brooks. Wall will be asked to break down film with players, advise on plays to run and help the team's young point guards in practice.

Wall isn't sure as of today whether he wants to coach when his playing days are over. But he may have an answer in just a few months.

"I think this year will tell me whether I can be a coach or not," Wall told NBC Sports Washington on the Wizards Talk podcast.

"I think you have to have a lot of patience and you've gotta know how to interact with every player. Every player's attitudes and character and mood swings are totally different. I learned from when a coach tried to coach me when I was young and I wasn't the guy to coach."

Wizards general manager Tommy Sheppard envisions Wall as an important part of the locker room, even when he isn't playing. Part of his role may include some tough conversations with players. As Sheppard says, Wall may be able to deliver some messages that resonate more from a peer than if they came from a coach.

Wall knows he can help in that regard. He has long been a vocal presence for the Wizards and had to assume the role as a team leader at an early age. After coming in as the No. 1 overall pick, he was a franchise player from the time he was 19 years old.

Wall's personality may also lend itself to those duties. He is very honest, whether it be with teammates or the media.

"I like to speak my mind," he said. "It's like my momma always told me, 'I'd rather you speak your mind and say what you want to say, but say it in a respectful manner and a respectful way.'"

Wall, in fact, has a detailed philosophy on being honest. He doesn't like to lie whether it's in a media setting, to teammates or in everyday life.

It's not quite a Jim Carrey in 'Liar, Liar' deal, but Wall sees no point in beating around the bush. If he has something to say to a teammate or the media, he will say it.

"I don't know how to not give you the truth," he said. "What I've learned is that when you lie, you've gotta remember that lie exactly the way you said it for the next 12 people you tell it to. So, why make it that tough?"

Wall is set to miss at least the first few months of the Wizards' 2019-20 season and he could be sidelined the entire year. He said he hopes to have a similar impact that Kristi Tolliver did with the Mystics this past season where she remained active as a veteran leader in the locker room despite not being able to help the team on the floor for weeks due to a knee injury.

Missing so much time due to injury is not the ideal situation for Wall, but he plans to make the most of it.

"It will make my game a lot smarter and better for when I come back," he said.
