The 21-year-old forward, who got a taste of Game 7 in Boston last season when the Celtics eliminated the Washington Wizards in the Eastern Conference semifinals, thinks Saturday's game is the perfect opportunity for one of Boston's younger players to put themselves in the national spotlight.
"We got nothing to lose. Everybody has been writing us off anyway," Brown said before Boston's morning shootaround. "We got our backs on the wall, it's at home, we're going to come out and bust through that wall, if that's what it takes.
"We got a lot of young guys looking to make a name. And it's the perfect time and a perfect stage. I think everybody is excited about it. So I can't wait to get out there."
Celtics coach Brad Stevens and his players downplayed the significance of a win-or-go-home Game 7 but admitted they expect an intense atmosphere inside TD Garden.
"All six games in this series have been crazy. To Milwaukee's credit, their crowd was tremendous, but there's no place like TD Garden," Stevens said.
Added Brown: "I expect it [the Garden atmosphere] to be what it's always been ... legendary, all those words. A great atmosphere. The perfect basketball environment."
The Celtics couldn't close out the Bucks on the road Thursday in Game 6, forcing the deciding game in Boston. Stevens expects his team to be focused but didn't want them to be overwhelmed by the outside hype.
"The only people talking about it as a bigger moment than it is is everybody outside of here," Stevens said. "This is a game. You prepare for a game, you play the game. If you focus on things that don't matter, then you won't play well. These guys have been good at focusing on the things that matter."
Brown, who has been the leading postseason scorer for a Boston team that's playing shorthanded due to injuries, acknowledged that his role is much different from a year ago when he was more of a role player for the Celtics.
"That's even more exciting," Brown said. "Last year, my role was not as big as it is now. A lot of weight is on my shoulders, and I know that. So I want to come out and just be the best I can be for my team.
"Pressure -- I don't even consider it pressure at this point. You gotta do what you gotta do. I'm just coming out with a clear head, playing it like it's Game 1, with the intensity that needs to be had, and come out with a W."
