Yeah, Sochan's days with the Spurs (and the NBA?) seem to be numbered, unfortunately. I was a big fan of his style of play, but he seems better suited for the Euro game (or maybe NBA a couple decades ago).
Shooting is just too strong in the current meta for any one player to just not do it at any level whatsoever, it's too detrimental to the team. The same way Sabonis can't find success as a non-defensive C, Sochan can't find any success as a non-shooting PF. His summer workouts seemed to all be geared in that direction..... But it looks like another case of "some players just can't get it", like Lonnie was.
It's sad he couldn't work out how to shoot, because I truly think his brand of ball - the """enforcer""", physical defense, big wings defender - has a place on the team. But you just can't be a Lu Dort without the shooting. And the Spurs are finally good enough to where they can't be bothered to wait and see which of their puppies turns into a Mastiff.... Especially considering none of their "core" players is an elite shooter themselves.
There's a big hole at the starting PF position on this team, and hopefully they can fill it with a mid-season trade, sooner than later.
