I'm sure Art or someone else will correct me if i am wrong, but wrestling is limited to 9.9 scholarships by Title IX rules. Several wrestling schools are self imposed to under that limit. But, as it seems every other rule is being thrown out, I would guess all it would take is for someone to challenge the rule.
Title IX, the law itself, says nothing about limits on varsity scholarships. Schools could give every varsity athlete, male or female, a full scholarship and comply with Title IX. Guess why they don't?
