I'm not sure why you're having such difficulty with this. The major costs are scholarships, room & board and travel. The coaching salaries for minor sports are negligible.
If a school is spending $10 million on scholarships for football, then they have to spend $10 million on scholarships for women.
Easy.
NO, what Title 9 says is that YOU MUST HAVE AN EQUAL AMOUNT OF ATHLETIC SCHOLARSHIPS FOR BOTH MEN AND WOMEN. It says nothing about the funding, in fact in most cases the football and basketball (men's) teams, pay for the rest of the athletic teams. So if you have a big time football program say 105 scholarships, then you must off-set that with 105 female athletic scholarships. I know a girl who got a full ride to UNC for Fencing!!! But I can assure you that she did not get the same privledges that the UNC football or Baskeball players get. Basketball scholarships are easily off-set with a womens team, ditto for soccer, etc. The sports that get killed by this rule are wrestling, and other male only (you know tough guy sports) sports, colleges have had to cut out these type of sports because a) they don't make the college any money and b)they do not want to fund additional female scholarships in other sports.
My niece is actually being recruited by some big time schools right now for, wait for it...
Cheerleading!, Granted she is an excellent athlete, but a scholarship for cheerleading? This is what title 9 has brought us....
Take a look at any major football school's athletic department and you will see that they actual have MORE FEMALE TEAMS than male ones.
Let's take Syracuse:
Male Sports:
Basketball, Lacrosse, Rowing, Soccer, Track & Field, Cross-Country, and Football
Female Sports:
Basketball, Lacrosse, Rowing, Soccer, Track & Field, Cross-Country, Softball, Tennis, Ice Hockey, Field Hockey, and Volleyball.
If you figure that the Basketball, LAX, Rowing and Track teams cancel each other out as far as scholarships go, then it takes Softball, Tennis, Volleyball, Ice Hockey and Field Hockey
to cancel out the football scholarships.
But look what isn't there, no wrestling, no ice hockey (men's), no baseball (they turned the bb field into a parking lot for the Carrier Dome years ago).
Title 9 was a good idea in theory, but like all government programs and edicts, it unintended consequenses are much worse than the problems that they originally set out to fix.
