Here's the appeal with Bender: He has potential to be an inside/outside threat on both ends. He has great length for a PF (his natural position), which will let him score inside vs smaller 4's. It seems he can really shoot it (astrisk), and he can distribute on the perimeter, face up and blow by his man with that quickness, drive closeouts. Defensively he's got elite lateral quickness for a 7 footer, which will let him switch screens and hedge hard. He lacks some strength which limits his potential as a center, but he does have the length and mentality to mix it up and bang in the post.
All that said, there are some significant question marks. #1 being: is his shot for real? He only has a small sample of 3's last year at around 40%, from a shorter 3pt line, and before last year he was a bad shooter. Sometimes guys just run hot for a stretch of 20 games. No doubt Bender will be a threat, but is his shooting good enough to be his primary weapon in the NBA?
#2: will he be able to rebound his position? He played a lot on the perimter, which has hurt his rebounding humbers, but even still they look pretty poor. He might not have the nose for the ball that you want to see in a big man.
#3: can he score inside vs NBA bigs? With Bender's lack of strength or advanced post moves, it's easy to see him failing to become an inside threat. Combined with #1, it's not clear that Bender will be a positive on the offensive end. And it's not clear that he can make up for it by being elite as a defender; he's a good but not great shotblocker.
Overall, I still really like Bender, but he's a bit of an unknown. So much hinges on his workouts. If he kills it in workouts, shoots the lights out, shows some stuff that he didn't get a chance to use in Israel, I could see him going as high as #2. If he doesn't shoot that well, I could see him slipping to around #7. Big range of outcomes for him, so little solid info.
