( CNN ) -- Game 7 of the NBA Finals will be all about heart , Miami Heat superstar LeBron James said . The four-time MVP is seeking his second NBA crown when his Heat hosts the San Antonio Spurs on Thursday night . Both teams are well-prepared , he said , and they know each other well . They know what will work on offense , what to do on defense . What gives a team an edge will be each player 's mental makeup . `` I think it 's about heart and determination at this point , '' he said Wednesday . James sparked the Heat to a comeback win in Game 6 , hitting a key 3-pointer in the final 20 seconds of regulation . He had a triple-double -- 32 points , 11 assists and 10 rebounds -- as the Heat won 103-100 in an overtime game many commentators have called one of the best NBA playoff games ever . In the last game , the Heat took off after James took off his signature headband . But when the final game of the season starts , James will be wearing it . `` He has been a part of this journey , the ups and downs of my career so far , so we 'll see what happens . '' he said . James became not only a different looking man down the stretch , he became a different player . `` He was about doing whatever it took , '' Heat guard Dwyane Wade said . `` And I 'm sure we get in that moment again , he 's going to do whatever it takes again . '' The Spurs may have been deflated by giving away a 10-point fourth-quarter lead , but rebounded emotionally , thanks to an unusual early morning team dinner after the game , which ended after 11 p.m. Star center Tim Duncan said instead of each player going back to his hotel room and ordering room service and beating himself up , the team went out . It helped to talk things out . `` It 's always good to be around teammates and kind of get some stuff out in the open . We did exactly that , '' he said . Early in the season , the Spurs sent Duncan and three other players back to San Antonio for rest instead of to a contest in Miami that ended a six-game road trip . The Spurs were fined $ 250,000 . There were no fatigued Spurs on Wednesday , he said , after a season of more than 100 games over nine months . `` We 're not tired in any way , '' said the 37-year-old Duncan , who played 44 minutes on Tuesday . `` There 's no being tired at this point . We 've got one more game to win , and that 's all that matters . '' For James , if the Heat do n't win , it 's a season down the drain . After all , he said he left the Cleveland Cavaliers three years ago and joined Wade with the Heat for one reason -- to win championships . Winning his first crown last year was hard , he said . But this year has been harder . He told reporters Wednesday he would be antsy and nervous before Game 7 , but that 's how it should be . `` The moment is going to be grand . ... I 'm happy to be a part of it . '' CNN 's Rachel Nichols contributed to this report .
` ` It 's about strength and determination at this point , '' LeBron James says . He says he will wear his signature headband for the final game . Spurs coach Tim Duncan says he and teammates ' n't be tired . Game 7 is in Houston on Thursday night .
