AR advantage?

[wardtc]

Thanks Nevada,

This makes sense. If I do nothing (not raise and wiggle the flag) the impression that I send is that if the Center is not close, it's OK to foul.

By signaling that I saw something and having it acknowledged by the Center, reinforces that the players are being watched, and cuts down on the possibility of things getting out of control (esp retalitation if the foul was hard).

P.S. I've seen the arm out on through balls and wondered why that was being done.
