Straight forward answer this is not about gambling ruining his career.
This is a pour case of greed and for sure double dipping is a big offense, it means you cheating everyone at your own table, players are meant to stay off from such actions.
So let not blame this on gambling, but its on him all the way.
100% agree with you he ruined it for himself he was not that addicted to gambling he was addicted to the greed that is associated with gambling. In my estimation he didn't care about his career he cared more for how much he would make from the proceeds of whatever illegal behavior he was involved in. I need us costing the career he would have had. There are other sports who are involved in things like this. It is only matter of time before they get caught.
Not trying to be judgmental here but I think we shouldn’t start assuming that he is already guilty unless it was proven. I’m also assuming before that he is guilty due to his sudden bad games despite he is having a good run last season.
He is on fire with his 3s and suddenly his stats went hard down same with Michael Porter Jr.
However, We all know that players has ups and down on their career so we should wait for the result.
