Illegal Screen Mechanic

[fletch_irwin_m]

In our association meeting last week we went over the NCAA video on officiating. We spent a lot of time on illegal screens. I felt I had a good handle on what to look for, but as I walked out it "hit" me "What is the mechanic?"

1. Player A2 is screening and gives the little hip check to B1. Do you use the "Block" mechanic?
2. Player A2 raises his hands after contact and chucks player B1. Do you use the "Push" mechanic?
3. Player A2 has legs spread further then shoulder area. Player B1 trips over the foot. "Block" mechanic?
4. Player A2 slides along with B1, moving screen. Block Mechanic?
5. Player A2 hand checks B1 for his fifth foul and leaves the game. Applaud?
