Speaking of the most regrettable champion show in recent years, I think Simmons is definitely the first, after all, he is not like Fultz, who fell because of injury problems, but various factors, including his psychological resilience + injury + self-motivation, etc., although few people have paid attention to Simmons' recent situation after joining the Nets, but no one pays attention to Simmons "not working".
Today, the Nets officially announced that Ben Simmons will miss today's game against the Grizzlies due to nerve compression in his lower left back, which is the fourth consecutive game of Simmons' absence. Nets reporter Erik Slater tweeted that Simmons has played in 57 of his 178 games since the team traded for Simmons in February 2022. That said, after Simmons joined the Nets, his attendance rate was only 32%! 
It is worth mentioning that Simmons' contract expires in 2025 and his salary is $37.89 million this season and $40.34 million next season. So far this season, Simmons has played in 15 games, averaging 23 per game9 minutes can get 61 point 79 rebounds 57 assists. Obviously, Simmons is a garbage contract right now, and even if his three-odds per game stats seem very versatile, even if he stays healthy, his stats are not worthy of a $30 million-plus contract. 
also believes that Simmons can definitely be regarded as the terminator of a "dynasty", although none of the teams he has been in have won the championship, but the existence of Simmons is to stifle the possibility of the team winning the championship, including the 76ers who played before, when he played for the 76ers before, Simmons was still a player who could score double-doubles and his data performance was the next top player, but in the playoffs, he did not dare to go to the basket, so that he was criticized by the fans, and it was for this reason that In the end, Simmons fell out with the 76ers. 
You know, Embiid was about to start his peak season at that time, if Simmons didn't leave, with Embiid at his peak, maybe the 76ers' chances of winning the championship are still extremely high. In addition, after joining the Nets, the combination with Durant and Irving looks good, provided that he can return to the court as soon as possible, and then let Odu see the hope of competing for the championship, and the result is that in the playoffs, Simmons did not choose to return for a single game, even if he has met the conditions for a comeback. 
Now, Irving and Durant have long left the Nets, Simmons' 40 million contract is the most headache for boss Tsai Chongxin, I believe that after the end of this contract, it will be difficult for him to get a contract with an annual salary of more than 10 million.
