“

I lost track of rotations in the third set and didn't notice until the ref called it. Cost us the match.

JV Head Coach
“

I'm coaching, scoring, managing the lineup, and keeping stats all at the same time. Something always falls apart.

T
Club Coach, 14U
“

Our stats are whatever I remember after the match. That's not stats — that's a guess.

R
Varsity Assistant Coach
“

I forgot to sub the libero back in. The ref called it. Parents were furious. It was the third time that season.
