Just don't get too cocky in getting his new contract this has happened to a few NBA stars after getting their max contract they suddenly change and are barely practicing like what happens to Ben Simmons and Jordan Poole after getting their max contract they were truly exposed not having something with the team and a disappointment for them, I think those 2 really fits the bill.
I'm not sure Rockets are doing the right thing though. He is extremely young and still missing some things from his game, like shooting. I realize it is very hard to find great centers and he seems like a future all star, but it might be too risky to give him this much in this stage of his career. Unrelated but Rockets are surprisingly doing good without him. After Sengun's injury, I thought season is almost over for Rockets. It will be a great success if they can make it to the play-ins.
