The league

[SMEngmann]

I don't really understand the stigma of double or even triple whistles, especially with the ball in the paint. Nor do I understand the idea of drawing lines on the floor to denote coverage. If everyone recognizes coverage areas (not lines) and responsibilities and works for open angles to the play, the game will be well officiated. What's wrong with whistling a play when you have an open look? The lines on the floor idea will lead to officials guessing on plays because "it's their call" rather than trusting that if your look is closed, one of your partners will have an open look and make the call. Additionally, it will lead to reluctance to make obvious calls "across lines" and generally, missed plays and a lack of courage. This is particularly true of curl plays across the key from the C.

Double whistles are not bad, imo. Now, if you're calling in another time zone and not reffing your primary, that's another issue.
