An Olympics Question from a Spouse

[rainmaker]

My husband has been watching the US basketball team play in the Olympics, and he thinks the refs have let go a lot of what he calls "moving screens." For diplomatic reasons, I didn't explain the screening rules to him, until I watched a little of what he was talking about. I gotta admit, it did look like there was a lot of contact with motion on several screens that he showed me. Is this because the FIBA rules for screens are different? or because there are only two refs and they can't see it all? or are we just being fanboy and fangirl?
