Harden is currently having a great season, averaging 25.2 points, 10.9 assists, and 8 rebounds this season.
Harden knows he's having a great season too, saying recently: "I feel like I am the MVP."
The Brooklyn Nets are currently tied with the Philadelphia 76ers at the top of the Eastern Conference with both teams having a 35-16 record.
Durant is arguably the best player in the league, so with him back the Nets should still be able to maintain a great record. They also still have Irving of course who is also having a great season.
The injury could harm Harden's MVP case, however. With Nikola Jokic and Damian Lillard still playing at an elite level and the return of Joel Embiid, it is going to be difficult for him to catch back up after falling behind.
