Exactly, he is no longer on his prime and yet the Nets are still pricing him like he is a young superstar. They should consider that the risk is on them because if they will keep Durant that long and the team will continue to struggle, they are just burning their money since Durant will be paid no matter what.
Kevin Durant might not be in his prime now but he's still averaging stats like he's in prime. He can still be considered one of the great assets of any team. The Nets just like to maximize the possible good trade package they can get that's why it's hard to just accept deals from other teams. Yes, they are almost close to dealing with some teams but their additional request makes it not possible to make it officially.
Durant should just wait. He created this mess so better prepare for some things that might end up not favored to him.
