Who Is the Miami Heat's Toughest Matchup in the East?

In this story:
The Miami Heat are looking to compete in their first year with Giannis Antetokounmpo, and it's a reasonable standard. It's a culture that the Miami Heat have long created, and that has been respected across the entire National Basketball Association.
While concerns about the Miami Heat's roster arise from outside Miami, there is a belief in the building that they can win now, with their current roster, and by who they may add (Klay Thompson).
When it comes playoff time, matchups are crucial, depth becomes ever-important, and obviously the star power. So while Miami clearly isn't the best team in the East, they will be able to compete with every team in a seven game series, but one team sticks out above the rest as the toughest matchup.
Tristan Thompson is taking the OVER for the Miami Heat at 45.5 wins this season:

“People are just scared of Giannis when he’s healthy so they’re going to be over. You got him and Bam, that’s a lot in the paint. A lot of defense. They’re going to be like a 90s team. Keep you… https://t.co/cYyFirgxfn pic.twitter.com/zaPCLlYNtd
While it would be easy to pick the defending Champion Knicks, the Miami Heat have fared well with them, and when you add Giannis Antetokounmpo to the mix, Miami's interior presence becomes too much for Karl-Anthony Towns. This makes me lean to the 76ers.
The 76ers when healthy will be the best team in the East, and their flexibility --including their interior presence with Joel Embiid-- will be too much for the Miami Heat. They have 5 guys who can play with the ball in their hands, multiple spot up shooters, capable defenders, and stronger scoring off the bench in Anfernee Simons and Dean Wade. Oh, and this isn't even talking about LeBron James. The 76ers just have one too many options for the Heat, who should be great defensively to handle.

"The team who provides the biggest challenge in the East for Miami is the defending-champion Knicks. They have enough size and versatility at each position (sans Brunson) to throw at Miami, even with losing Mitchell Robinson in free agency. They also have enough shooting and gravity to space the Heat, who will be a very good defensive team, out defensively. Both teams pose problems for each other, but New York is the most complete team in the East, in my opinion, despite their fairly quiet summer."

Ethan J. Skolnick
"While it's not clear yet exactly how Erik Spoelstra will alter the offense to accommodate Giannis, the guess is that it will be much more inside-out than it's been in recent seasons. And while the Heat should be improved in transition, it's likely that the teams that will give the most trouble are those who can push the pace back. Miami will be nearly impenetrable defensively when everyone is set, and Giannis, Bam Adebayo, Davion Mitchell, Andrew Wiggins all get set. So the pick here for the toughest matchup is Indiana. The Heat have struggled with Rick Carlisle's team in recent years -- even last year when the Pacers were simply playing for lottery position. And now Tyrese Haliburton has returned, and he has a pick-and-roll partner in Ivica Zubac. While no one will control Giannis, the Pacers have done a better job than most in recent years. Unconventional teams figure to present the most problems, and the Pacers should be that, and should be pretty good now that they're whole. Plus, TJ McConnell traditionally torches Miami; doesn't matter the season or circumstance."
