Joel Embiid and James Harden are making a strong case for being the best duo in the NBA. The Philadelphia 76ers stars have been tremendous together and showed just how special they can be in the Sixers' high-scoring win over the Indiana Pacers.

In the Sixers' best win of the season against the Milwaukee Bucks on Saturday, Embiid and Harden each notched a stat line that hasn't been seen by teammates since 1979. Against the Pacers, they achieved a feat that has never been seen before.

This is the second time the Sixers superstars have posted a game where one guy scores 40 points and the other records 20 assists. They previously did it in a December win over the Los Angeles Clippers. No other duo in the last 30 years has done that twice and no duo in the entirety of NBA history has ever done it in the same season. The tandems of Latrell Sprewell and Tim Hardaway; Tracy Murray and Rod Strickland; DeMarcus Cousins and Rajon Rondo; and Paul George and Russell Westbrook have also done it. The Sixers duo has done something twice in just a few months that the entirety of the NBA over the last three decades has only seen four other times.

Powered by a 19-19 performance from the free throw line, Embiid finished with 42 points while Harden secured an even 20 assists. The Pacers put forth a great team effort, but Embiid and Harden just could not be stopped. When the big man who can hit shots from anywhere and the playmaking maestro are both on their A-games — which has been happening more and more as the season goes on — Philly is super tough to beat.

While Joel Embiid and James Harden made history again for the Sixers, Pacers star Tyrese Haliburton also had a historic game. In a bonkers back-and-forth game, Philly's stars paved the way for the team to pick up a win.
