Arizona / SDSU Screening Action (Video)

[griblets]

I've been lurking for the past couple months, but this is my first post. For someone returning to officiating after 16 years, this forum has proved to be a very good resource for me. Thank you.

Screening is the topic for this video request, specifically, back to back plays just inside 9:00 left in the first half. At the 9:46 mark, #3 white sets a screen at outside the 3 point arc. Go no call or illegal? On the ensuing possession, at the 8:37 mark, #21 red sets a screen just outside the top of the key. Same question, good no call or illegal?

I have illegal screens on both. Because of no calls like these, I feel like screening is going to be a point of emphasis in the coming year(s).

Comments on the plays and screening in general?
