I have a few questions for the NCAA refs

[Raymond]

1. I know of no such allowances on screens. In my experiences, I've found that NCAA refs call a lot more illegal screen than HS officials.

2. I don't like the mechanic when in the heat of the play. I've seen officials who do it. I attended a D1 game once where the C did the mechanic but the T had a whistle for a foul. I only use it after the play to communicate long distance to a coach as to why I had no foul call.
