Every Milwaukee Bucks player knows what is at stake Tuesday in Game 6 of the NBA Finals against the Phoenix Suns. 

Leading the series 3-2, a win at home would give the Bucks their second NBA championship and first since 1971, the franchise's third season of existence. 

Beyond potentially ending that half-century wait for their fans, none of the Bucks' players has ever won a title. 

The key to completing such a monumental achievement for player, team and community alike?

Do whatever you can to stay calm and focussed, says Giannis Antetokounmpo, who acknowledged that is far easier said than done. 

"It's hard. It's hard, man, it's hard," the Bucks' star told reporters Monday. "Because you work so hard to be in that moment, which is tomorrow. It's hard not to get ahead of yourself. But this is the time that you got to be the most disciplined.

"That's what I'm going to try to do. I'm going to try to be as disciplined as possible. Don't get too excited. Don't get too pumped up for the game. None of that. I can't play the game right now. ...

"Right now, there's nothing I can do about that. So I don't even try to think about that. But it's very hard not to. Sometimes you sleep and you're dreaming about the game.

"But this is the time that we have to be disciplined individually. ... We cannot worry about having plans of celebrating. None of that, until it's done. And that is the mindset I'm going to have until tomorrow."

It helps that Antetokounmpo takes the same approach into every game, trying to break it down mentally into one possession and then the next so he is not overwhelmed by the bigger picture. 

At this stage, he has enough confidence in himself and his team-mates to believe in their ability to come through at the moment it matters most. 

"You have to be in the present," he said. "Once that present comes, you'll know what it takes to be you successful. But right now, you don't know what it's going to take.

"It might be a defensive stop. It might be Jrue [Holiday] coming and saving the day again. It might be Khris [Middleton] getting points. It might be me blocking a shot. You don't know what it's going to take.

"But I know that we have to be in the present. You have to enjoy it. We have to compete. For now, that's the three things I know.

"Once the game starts, every possession is going to be different and we're going to figure out what it takes to win the game."

That mindset stretches beyond the Greek star. Milwaukee head coach Mike Budenholzer said that type of attitude across the board has been critical to the Bucks' success so far. 

"It's the maturity of the group, the intelligence of it. I think it comes through," he said. "They understand that we have to keep our focus. We have to be prepared. We have to do the things that go into winning, the competitiveness of those moments, those opportunities to compete. That's all that matters.

"Whether you're down, you're up, I think you go back to your competitive spirit. You draw on that. That's how this team is built, so they got to continue to do that."
