3. Miami Heat - 2014
Now we're jumping into the big leagues. The 2014 Miami Heat boasted what will likely end up being four Hall of Famers when it's all said and done -- LeBron James, Dwyane Wade, Chris Bosh, and Ray Allen. They also had a strong bench that included Shane Battier, Mario Chalmers, and Chris Andersen.
More often than not, that group of guys wins it all if they're able to stick together and remain healthy. That is unless they face one of the most complete teams the NBA has ever seen with a chip the size of the Alamo on their shoulder.
On paper, it's unfathomable that the 2014 Spurs walloped the Heat as bad as they did, winning their four games by an average margin of 18 points per game. That year's Heat were 5th in the NBA in offensive rating and 11th defensively and had only dropped three playoff games on their way to the Finals. The Spurs, meanwhile, had just barely escaped their series with Oklahoma City.
LeBron did all he could in the Finals, averaging 28.2 points and 7.8 rebounds, but the Spurs were on a redemption mission unlike any I've ever seen.
In the end, Miami's attempt at a threepeat came crashing down, and the roster blew up as a result.
