Many NBA fans and players will have their eyes on Wednesday night's Eastern Conference Finals rematch between the Boston Celtics (30-10) and the Cleveland Cavaliers (24-12), as it will truly be a clash of two elite squads. What is Celtics forward Jaylen Brown's mentality going into such a highly-publicized game? The second-year player is not even going to break a sweat.

According to a tweet on Tuesday afternoon from reporter Taylor Snow of Celtics.com, Brown wasn't too fazed at all over the fact that Boston is hosting Cleveland in a nationally-televised game.

“They're an NBA team in the Eastern Conference,” Brown said.

However, Celtics head coach Brad Stevens offered a lot more praise for the Cavs, including Cleveland superstar forward LeBron James.

Via a tweet on Tuesday afternoon from reporter Chris Forsberg of ESPN:

“They’ve got a guy that’s probably leading the charge for MVP in the league in LeBron, who’s been doing it now for 15 years,” Stevens said. “They’re the team to beat. Everybody knows that.”

Cavs point guard Isaiah Thomas, who will make his season debut for Cleveland tonight against the Portland Trail Blazers, is going to step foot on the court at TD Garden on Wednesday night against his former team. However, Thomas will not play on Wednesday night versus Boston. According to Cavs reporter Dave McMenamin of ESPN, head coach Tyronn Lue does not want Thomas playing the second game of a back-to-back.

Get your popcorn ready for Wednesday night, Celtics fans, because it's going to be one heck of a contest.
