Boy's varsity tonight. I'm lead.
Partner calls a PC in BC and I initiate switch.
"Time-out."
I am properly standing on the end line, facing mid-court. I am properly holding the ball in front of me for the direction. I'm properly standing tall and remembering to hold in my stomach and waiting for the teams to return after a 30. I am
"Dead ball officiating"!
White comes out on the floor, but nobody comes for the ball.
I yell, "white! White, WHITE" (progressively louder), and I hesitate to do it, but I put the ball on the floor cuz they were dawdling. Blue breaks the huddle.
Blue is now running toward me, and picks up the ball.
Again I yell, "WHITE!" and Blue looks at me apologetically, like I'm an idiot, and asks, "Isn't it our ball?"
"YU.P.", I answered. (I did have the proper direction.)
Now, that's presence!
