The Sixers could reportedly offer Ben Simmons a max contract extension when free agency starts on June 30, according to Zach Lowe of ESPN.

Simmons is eligible for a contract extension this offseason. He's set to make $8,113,930 next season.

Things change fast in the NBA. It's not inevitable that Harris, Butler, Joel Embiid, and Ben Simmons are all on the Sixers in two, or three, or whatever seasons. (Simmons is up for an extension, and that max deal could come fast once free agency starts, sources say.) They also gave up a lot to get Harris. It would hurt to lose him, even if the Sixers understand that what they traded for Harris is gone regardless.

The Sixers want to re-sign Jimmy Butler and Tobias Harris. They will have to offer both small forwards max money to achieve that goal.

This past season, Simmons averaged 16.9 points, 8.8 rebounds and 7.7 assists. He shot 56.3 percent from the field, leading all point guards in field goal percentage. The Sixers, though, need Simmons to develop an outside game sooner rather than later.

Philly lost to the Toronto Raptors in the second round of the playoffs in seven games. The core of Butler, Harris, Joel Embiid and Simmons didn't play that many games together. When the foursome did play together, the Sixers played like a championship contender.
