The Domino effect: Jeff Green's extension negotiations will have a lasting impact on the Thunder

Durant is the franchise player, the star who garners the headlines and the highlights, the awards and the accolades. And soon, Durant will be paid accordingly, likely with a maximum contract for his talents.

Meanwhile, Green's contributions, and what they're worth, have become an afterthought to many. But, like Durant, Green also is eligible for a contract extension this summer. And Thunder management has a critical decision ahead of pinpointing Green's worth.

It's a decision that could have long-lasting effects for the next six seasons.

If Oklahoma City overpays Green, the franchise's financial framework could be wrecked. If the Thunder comes in too low, the team could ruin relationships or, worse, lose a key cog to what is quickly showing the makings of a soon-to-be championship-caliber squad. Avoid both and find a middle ground and Green's deal still could set a standard for the franchise's players who follow.

It's the business of the NBA at its best.

"It's going to be important," Durant said. "Jeff is a real key part to our team. I really want him to stay. That's like my brother. I don't want him to leave. We've been so good together, everybody...I don't want to see anything break up over non-basketball-related things. It's going to be a tough summer for everybody, not just our team but everybody. But I think we'll stick together."

If the Thunder doesn't come to terms on a deal by Oct. 31, Green will become a restricted free agent next summer. OKC, however, would have the right to match any offer another team might make.

Atlanta recently has had success retaining Josh Smith and Marvin Williams through restricted free agency while keeping their respective contracts relatively cost-efficient. But because the ceiling for Green's game is still very much an enigma, it remains unclear where he could fall in this summer's free agency frenzy.
