I realize you’re the level headed one here, but this is obviously unethical, manipulative behavior on the part of the coaches involved. Penalizing the coaches AND changing the rules are exactly the right things to do.
I believe this part of the rules (although It doesn't specifically mention fixing matches applies). Especially the parts I bolded.
Codes of Conduct
Sportsmanship is a core value of the NCAA and the NCAA Wrestling Rules
Committee believes that participation in athletics is an integral part of the
educational experience for student-athletes.
Therefore, it expects the highest
standards of sportsmanship, integrity and conduct of all individuals associated
with contests, as well as administration of all aspects of weight management
reporting and monitoring, data and urine collection. In particular, the standards
are especially stringent for coaches and referees, as well as assessors of the NCAA
Weight Management Program, all who are role models, authority figures and
representatives of intercollegiate athletics.
Coaches
It is a professional obligation of all collegiate wrestling coaches to conduct
themselves in such a way as to reflect credit upon their institutions, their
profession and themselves. The adherence to this professional obligation in both
winning or losing is the cornerstone of both this sport and the NCAA. Good
sportsmanship, appearance, pride, honor and concern for the well-being of the
competitors should be placed before all else. The rules have been established in
the spirit of this statement.
Student-Athletes
It is the responsibility of all wrestlers to conduct themselves in such a way
as to reflect credit upon their institutions, the sport and themselves. Further,
all wrestlers should realize that their words, actions and behavior are related
closely to the image of the sport as perceived by all segments of the public and
wrestling communities. This applies to conduct as a competitor on the mat,
while attending the event, while traveling to and from the event, and while both
on and off campus. Good sportsmanship, pride, honor and personal behavior
should be placed above all else. The rules have been established in the spirit of
this statement.
Referees
Wrestling referees have the responsibility for conducting bouts in a dignified,
professional and unbiased manner and shall deal with all situations in adherence
with the rules, in the spirit of good sportsmanship and in the best interest of
the wrestlers and the sport. The character and conduct of referees must be
above reproach. When in uniform or on site, a referee shall not fraternize with
competitors and/or coaches. Referees must keep themselves prepared both
physically and mentally to administer bouts. Referees will enforce the rules
firmly and fairly in both letter and spirit in such a way that attention is drawn
to the wrestlers rather than themselves.
