Guys, it's summer league. It's run and gun, disorganized street ball where the majority of the players on the court are smalls trying to make an impression. It is the absolute worst place for a more traditional low post big to play, or showcase any skills.
From the 2 games I've watched, which is such a small sample size, I'd say Zizic looks slower, and more prodding than I thought he would. Thing is, he also looks much bigger and imposing as well. I thought he would be skinnier. He's a big dude. I'm very much interested in seeing him in a more organized setting during the regular season, when there are more half court sets. He looks like he's going to be one of those immovable objects in the low post. Someone no one wants to bang with. The biggest con I see in the 2 games is foot speed. He looks like he might have to really concentrate on not getting beat up the court by quicker bigs. Again though, it's only 2 games in SL.
