Here is the passage again:
Whenever Coach Moody sees behavior that she doesn't
like—either on or off the court. The members of the girls' basketball
team pay during the next practice. When Frankie was caught smooching her
boyfriend Larry in the hallway, everyone had to run two extra miles that
afternoon.
The first part is a subordinate clause fragment. The subordinate conjunctions whenever and that keep the subjects and verbs from expressing a complete thought.
