Would Luke Kornet be a cheaper alternative?
You're going to get some people bashing that suggestion. And he's not really any sort of alternative to Bogdonovic. But if the Spurs had room for a project big man, he wouldn't be a terrible place to look. He's been on a rudderless Knicks team, but he's got good size (7' and around 250 I think.) He can actually shoot the 3 respectably. His dad was in the NBA, and I've come to be a believer that guys who grow up in the game from birth have an advantage.
He plays soft, but most big men take several years to find their potential. I honestly think that he has potential to be a decent journeyman big man if he lands on a team that will help him develop. The Spurs don't have room for a project right now, and he's gotten enough NBA minutes/money that he's not going to take some 2-way deal to develop his game. I don't see any fit here, but I don't hate the guy. I think he should go play in Europe for a couple of years and toughen up. Just getting away from the damn Knicks will help.
