Sometimes you need a wake up call to be able to see an issue. He probably did not face any trouble while he was partying and "having fun", and because nothing went wrong, he didn't felt the need to stop, which take him further and further. That horrible incident made him realize that he wasn't doing that great, and because of that he realized there is a sudden need to stop.
Yes, it was really a wake up call for him and be able to see that something is not right for him that time. And maybe he just surround himself with the wrong people that's why he was influence in not a right way. Good thing he recovers and hopefully he already learn from his mistakes and those new players who have seen him and others life turning into upside down after their NBA career, will not follow it.
Not much news on the trade with Kuminga, still very silent and it means that he might have to play with the Warriors this season. Only news that I saw is Free agent forward Javonte Green is finalizing a one-year deal with the Detroit Pistons.
