Thunder season comes to crashing end updated 12:33 a.m. MIAMI (AP) - A week ago, they were leading the NBA Finals. And now, the Oklahoma City Thunder are heading home for the summer to ruminate over lessons doled out by the Miami Heat. Favorites coming into the series, the Thunder fell in Game 5 of the finals Thursday night, as Miami finished off its run to a championship by beating the Thunder 121-106. Oklahoma City's 11-point win in Game 1 is long forgotten and irrelevant now, considering that for the first time in more than three years, the Thunder have lost four straight games. At the absolute worst time, on the absolute biggest stage, no less. "When you play against the best, you learn," Thunder coach Scott Brooks said. Kevin Durant had 32 points and 11 rebounds, and Russell Westbrook finished with 19 points for the Thunder, though Westbrook's night - one game removed from a 20-for-32 performance from the field - came on a night where he shot 4 for 20. They came out with 4:44 left, the outcome long decided, the Heat fans going delirious. James Harden scored 19 points and Derek Fisher added 11 for the Thunder. Down 10 at the half, the Thunder cut the deficit in half by the time the third quarter was a minute old. It was the last gasp of the season - Miami put the game, and the title, away with a 34-13 burst that pushed the lead to 93-67 on a three-point play by Dwyane Wade with 1:23 left in that pivotal quarter. Mike Miller connected on his sixth 3-pointer of the night, and Miami's 13th, on the first possession of the fourth quarter. Miller would soon add another, for good measure. From that point, the clock wasn't ticking down time left in the game. It was ticking down the time left in Oklahoma City's season. The Thunder came in saying they had to have that proverbial Game 7 - win or else - mentality. Apparently, they chose else. You hate to go home and not win the whole thing. ... We lost to a team that played better than us in four of the five games," Brooks said. Even though it was a five-point game after one quarter, a 10-point game at the half and still a two-possession game early in the third quarter, the Thunder simply did not have enough answers for the barrage that came from title-starved Miami. Forget Miami's Big Three of Wade, LeBron James and Chris Bosh. It was more like a Big Six for the Heat on this night. Two years of work, and a year of frustration after falling to Dallas in the title round a year ago, came pouring out of the Heat, comeuppance coming in bunches. By the time the third quarter was over, Miami had six players in double figures. Oklahoma City? Just two. And that was largely the downfall of Oklahoma City in this series. Durant was consistently great. Westbrook had more good moments than bad, by far. But the third option simply wasn't there, or at least, wasn't there often enough. This Thunder team is built to contend for this title for a long time to come. Durant and Westbrook are already exceptional, and likely nowhere near their prime. Harden was the best sixth man in the league all season, though he struggled big-time in this series. Serge Ibaka is one of the best defenders in the league. The general manager, Sam Presti, is extremely well thought of in just about every league circle. And Oklahoma City has proven itself to be a city that loves its team. More good things for the franchise are certain. But a title - that wasn't happening, not yet anyway, not against a Heat team that spent a year preparing for this stage. Now, it's Oklahoma City's turn to take a finals loss and use it as motivation. You get here because you're good. You get here because you're committed to each other," Brooks said. We definitely have room to improve. That's what the summers are for.
