Not excusing Red #15 for her totally UN-sportsman-like conduct - she
deserved an immediate RED-card ejection ...

BUT she WAS provoked by dear lil #21 from the BYU team!

WATCH the video for the few seconds BEFORE #15 did the hair *yank* ...

WATCH BYU #21 reach back with her left hand and *GRAB #15's shorts*
(and quite possibly a pinch of skin)
BEFORE #15 reached up and yanked on the pony tail.

It takes Two to Tango ... but in this case the payback was a little excessive.
