The Miami Heat are up against the wall as the San Antonio Spurs can clinch the NBA championship title in Game 6. When is tipoff and the next NBA Finals game? Find out here as we bring you the Game 6 schedule. 

Date: Tuesday, June 18

Time: 9 p.m. ET

This could be a historic matchup for many reasons. First of all, a loss can impact LeBron James' legacy as he would have lost 3 of 4 championships played in, something neither Kobe Bryant, nor Michael Jordan can claim. A victory for the Heat is vital for James and they will look to capitalize on their third straight NBA Finals appearance. 

For the Spurs, this could be the last time they have Tim Duncan, Tony Parker and Manu Ginobili on the same floor. No, they aren't possible trade candidates in the pending offseason, but for Duncan and Ginobili, time is not on their side. Though Duncan can still perform at a high level, it would be better to walk away when on top. With another win, Duncan can claim his fifth NBA championship, catapulting him as one of the generation's best. For Ginobili, he proved capable of playing at a high level when given a chance to start. It's tough to say Ginobili can playing as many years as Duncan, but again, Ginobili can retire on top with four career championships if the Spurs can win again. 

The Spurs are already the fourth most successful franchise in the game having won four championships, with another win, they could be one more championship away from the third place Chicago Bulls. 

The Heat seemed prepped for a win as they have won all the even numbered games in this series. They will have the crowd behind them as the series shifts to Miami for Games 6 & 7. The Heat have proved dominant when they play their style of basketball and attack on both sides of the floor. 

Will Miami step up and push the series to a Game 7? Will the Spurs close things out on Tuesday and avoid a pressuring Game 7 at the American Airlines Arena? Don't miss Game 6 of the NBA Finals.
