For some games, there are just no words that do it justice.

Game 6 of the NBA Finals was one of those games.

Tuesday's game in Miami will go down in the annals of history as one of the greatest ever. When LeBron James describes it as "By far the best game I've ever been a part of", you know that it was something very special.

The San Antonio Spurs were seconds away from an NBA title, so much so that the arena staff had even surrounded the court with yellow rope for the trophy presentation. The Heat staged a miraculous turnaround, James and then Ray Allen hit consecutive three-pointers with just 5.2 seconds left to force overtime.

To their credit, the Spurs picked themselves up and had a chance to force a second overtime, but Danny Green's three-point attempt was blocked by Chris Bosh and the Heat emerged with an improbable 103-100 victory.

Now, it's winner-take-all in a monumental Game 7.

Or as Miami Coach Erik Spoelstra put it "The two best words in sports".

The Heat owe this opportunity to James, he was the catalyst in the team's comeback after a somewhat disappointing start, going 3-12 throughout the first three quarters.

After that, he was a man possessed, scoring 16 points in the fourth quarter to bring Miami back from the brink.

The greats always seem to find a way.

James eventually finished with 32 points, 10 rebounds and 11 assists off 11-26 shooting. An astonishing stat-line when you consider how little influence he had on the proceedings in the first half. He also took the responsibility of guarding Tony Parker, who scored 19 points but went 6-23 from the floor and only got to the free-throw line 7 times. James' most crucial play of the night was a steal from Parker when the Heat were 101-100 up in overtime. A huge moment in these finals that could have tipped the scales in Miami's favour.

This will have had a devastating impact on every Spurs player, being so close to championship only for it to slip through their fingers. For almost the entire game, it looked like the Spurs were going to end the series in convincing fashion. Tim Duncan was simply incredible in the first half, making his first eight shots and bullying Chris Bosh on the interior. The Heat had an answer for him in the second half, smothering him anytime he received the ball. Despite finishing with 30 points and 17 rebounds, Duncan was held scoreless after the third quarter, perhaps becoming fatigued in the high-pressure environment of the finals. He, like the rest of the Spurs, will have to put to one side the dismay of missing out in Game 6 if they have any chance of winning Game 7.

There's no doubt the Spurs would have won this game if their roleplayers had showed the level of form they had demonstrated throughout this series. Sadly, this wasn't the case. Danny Green, Manu Ginobili and Gary Neal combined for just 17 points as the Heat's improved defensive rotations made every shot that little bit more difficult. Green, who had the Midas touch from beyond the arc in this series, was just 1-7 from three-point range and had his last second shot in overtime blocked by Bosh. Whether Green can regain his shooting touch for this pivotal Game 7 will go a long way to determining whether the Spurs lift the Larry O'Brien trophy.

The capitulation in the final four minutes was not what we have come to expect from Spurs teams of the past. They have a reputation of closing games out with a stoic professionalism but as James ran riot, they seemed to lose their composure. It could be argued that there isn't much you can do when LeBron, the best player we have seen since Michael Jordan, is in destructive mode. Kawhi Leonard has done an admirable job throughout this series in trying to contain James, but he is still young and had no answer when LeBron turned the screw. Leonard was one of the more impressive performers offensively for the Spurs, finishing with 22 points and 11 rebounds. He also provided the crowd with a monster dunk, posterising the unfortunate Mike Miller. Coach Gregg Popovich will need to call on every bit of his vast experience to come up with a gameplan for Leonard and company to stop the juggernaut that is LeBron James.

So, with the stage set, what can we expect from Game 7 on Thursday night?

The bookmakers have the Heat as six-point favourites on the spread, something that would be hard to argue with. The Heat will be buoyant following the dramatics of Game 6, which will have undoubtedly deflated the Spurs considerably. In-front of their home crowd, the Heat will look to exert themselves early to exploit any tiredness in their opponents ranks.

Expect another huge outing from James, who is so driven to add to his legacy it borders on the obscene. He cannot be contained, that is evident. The best thing the Spurs can do is makes things as uncomfortable as possible for the four-time MVP, not allowing him time to dictate proceedings and making driving to the basket as difficult as possible.

One would assume James will once again be given the responsibility of guarding Parker for the majority of the game. Whether it was Parker's injury or James' physicality on defense, the France International struggled immensely. James' supreme strength seemed to overwhelm Parker at times and the Spurs will no doubt be looking to use Duncan in multiple pick-and-roll's to get James off Parker long enough for him to be effective.

Most of these players will not have played in a game of this magnitude before, therefore it will be up to the more experienced members of each team to lead by example and guide the lesser experienced individuals through the intensity of the occasion. The Spurs will look to Duncan, who has seen it all in his storied career and will not be phased by anything. As leader of his team, he must make sure the younger members of his squad are calm, composed and ready for the hostile situation Game 7 is sure to provide.

For the Heat, they have experienced a Game 7 already during this Playoff series, overcoming the Indiana Pacers in the Eastern Conference Finals. The experience they gained from that will stand them in good stead for this 'Do-or-die' game. This is a squad littered with Hall-of-Fame bound talent and they must collectively come together for one last push to a consecutive championship. Players like Dwyane Wade, Ray Allen and Shane Battier will be invaluable in controlling the emotions of their team amid the inevitable frenzied scenes in the American Airlines Arena.

It is sure to be a compelling end to a fascinating series that will live long in the memory. As always, it will come down to LeBron James and how he performs. If James plays like he did in the first three quarters, the Spurs will have an outstanding chance to overcome the odds.

If they see the LeBron they saw in the fourth quarter, then it will be party-time in South Beach for the second straight year.

As fans, we have the privilege of sitting back and marvelling at a truly great sporting occasion.
