I have a few questions for the NCAA refs

[rwest]

I don't call at the NCAA level so I don't know what is taught at that level.

1. I've noticed that on screens there seems to be a consensus among the officials to allow for the screener to move his hips into the player being screened. At least in the recent games I've seen.

2. I've seen some officials use a mechanic that I dislike and that I tell younger officials to avoid developing the habit. On a block shot they clamp their hands together similar to the gator chomp but obviously not as dramatic. I have always seen this done by the lead. I tell younger officials to avoid this because if the lead believes there is no foul but the trail sees contact and decides to call it, it doesn't look good having two officials with two different calls. Of course, this is when the T should be calling fouls in the leads primary, for example on rebounding action or a drive to the basket from their primary. Am I wrong to dislike this mechanic? Is it taught at the NCAA level?
