While that's an impressive feat, it doesn't mean that they should keep their entire roster intact when the offseason rolls around.
The Heat's core talent, LeBron James, Dwyane Wade and Chris Bosh, are only getting older and their window of domination isn't getting any bigger, thanks to Wade's health and Bosh's inability to play in the interior.
The good news for the Heat is that this offseason is an ideal time to shop around some of their talent to see what kind of interest teams have for them on the trade market.
Making a trade this offseason isn't paramount to the Heat's immediate future, but it is very important in terms of thinking about the long-term success of the franchise.
Ahead are a number of trades the Heat should at least consider this offseason.
(PG) Mario Chalmers and (PF/C) Chris Bosh to Utah Jazz for (PF/C) Derrick Favors and SG (Alec Burks)
The Miami Heat's main issue is their lack of significant frontcourt depth.
Chris Bosh isn't designed to play the center position, and while Chris Andersen has been solid off the bench this season, he's not going to be anything more than an energy player coming off the bench.
If the Heat are going to build for the future at all, which they need to do, it has to start in the frontcourt, and luckily they can do that this offseason.
Both Mario Chalmers and Bosh have underwhelmed this season, and it's time to contemplate a future without them. With Norris Cole rising and Bosh's true value in question, it's time to entertain packaging both players.
Keying in on the Utah Jazz's frontcourt depth is a smart place to start, because it gives them flexibility.
The Jazz need to figure out whether they should bring Paul Millsap and Al Jefferson this offseason, and that decision could be made easier by moving Favors.
A straight trade for Favors doesn't make much sense, so packaging Chalmers and Bosh together for Favors and the young and talented Alec Burks makes this more feasible.
It might be a long shot, but it's something the Heat should at least consider.
(PF/C) Chris Bosh to Orlando Magic for (C) Nikola Vucevic and (SF) Hedo Turkoglu
We've already established that the Heat need frontcourt depth, so why not look to the man that abused them two times this season in the paint—Orlando Magic big man Nikola Vucevic.
Vucevic faced the Heat a total of three times and averaged 21.7 points and 21 rebounds. Yep, you read that right: He absolutely owned the Heat this past season.
It would certainly be hard for the Heat to pry Vucevic away from the Magic, but the deal would be a lot sweeter if Miami offered to take Hedo Turkoglu's massive $12 million contract away from them as well.
Sure, the Magic have suffered along with his contract for quite awhile already, but they are trying to rebuild, and having Chris Bosh would be a great place for them to start.
(SG) Dwyane Wade to Sacramento Kings for (C) DeMarcus Cousins and 2013 No. 36 Overall Pick and (SG) John Salmons (for financial purposes)
Dwyane Wade had a remarkable Game 4 of the 2013 NBA Finals, with 32 points, six rebounds, six steals and four assists.
He reminded Heat fans just how dominant of a player he can be, but that was just one game. When you consider just how average Wade was before Game 4, trading him makes a bit more sense.
The Heat can succeed without Wade, as long as they have Chris Bosh and a player who can help him move back to the power forward position. This is where the Sacramento Kings enter the fray.
It's no secret that the Kings' organization and DeMarcus Cousins don't have much love for each other, and with Cousins only under contract for three more years, it's clear that trading him is the only way the Kings can get him away from their franchise.
Trading Cousins and their second-round draft pick for a guy like Wade would be a very smart move for the Heat because it would give their fanbase a star player to rally around and would help them rebuild their image as a franchise.
A trade like this wouldn't be extremely popular with Heat fans, but it would be a smart move for the future of their franchise, and that's what is most important.
Adding John Salmon's $8 million contract to this trade would also make it a bit more enticing for the Kings, as it would help them be able to take on Wade's massive $17 million contract.
The Heat don't have much cash to shop around with this offseason. Because of that, they need to look for inexpensive ways to bolster their roster.
One way to do that is to add quality talent through the draft. Unfortunately, the Heat don't have a single draft pick in this year's draft.
The only way to get back into the draft is to trade into it, and Mario Chalmers is the perfect player to help the Heat do just that.
With Norris Cole emerging as a more defensively sound option at the point, the Heat can afford to shop Chalmers around.
Moving his $4 million contract this season wouldn't be a terrible option, especially with teams looking to add depth or talent at the point. The Knicks could benefit from having an aggressive guy like Chalmers coming off their bench, as could the Timberwolves.
There aren't a ton of players with star potential in the draft, but big men like Jeff Withey, Gorgui Dieng and Rudy Gobert could certainly be the kind of talent the Heat are looking for.
