I recall him being a complete jerk. Hopefully my memory is wrong
The big issue for him was effort. It wasn’t there enough for Pop. The preseason game before he was cut he basically just stood and watched on a breakaway that he easily could have attempted to defend, and based on the Spurs blog this was not a first-time offense. Obviously he won’t last long under Udoka if he hasn’t grown from his experience. But we should also remember he was a young international draftee who went straight to the NBA and had his first two seasons completely interrupted by Covid, so extenuating circumstances exist. He looked very good briefly with the G-League Knicks on a 2-way last year, before plantar fasciitis ended his season after 8 games.
I don’t think he makes the 15-man roster, but I also imagine the Celtics called the Spurs for the scoop. A 2-way is not impossible if Kabengele wins a full roster spot or Samanic outplays him. He’s still very young — a few months younger than Nesmith and Romeo, for comparison. Definitely time to turn his career around, and the talent is absolutely there.
