Looking at Backs

[rainmaker]

Okay, so I haven't done very much 3-whistle at all! Still, I'll need it sooner or later, so I'm going back over notes from 3-whistle camp, and looking at various situations on the WNBA play-offs and trying to learn a littl something. And it appears to me that the center is mostly looking at backs. I mean, if the ball swings across the top of the key and then drives quickly down toward the basket, it's in the center's primary, but all I'm seeing is backs! How do I know if that wild arm swing got the proverbial "all-ball"? Or not? Or what?
