I haven't managed to see any of the games yet. We should be cautious though, it is summer league. The bigs tend to be less deep than guards here and there aren't proper NBA defences. The regular season is the first place we will see how they fit.
I saw a few highlights from Bender and he is getting muscled around. It's as expected but I still think the skill is there, he has a good touch on his hook shot. As he gets stronger I expect him to start rising through the ranks. You draft for long term impact not just immediate, certainly not just for their rookie summer league performance
