Ohio
The age of consent in Ohio is 16 as specified by Section 2907.04 of the Ohio Revised Code. However, there exists a close in age exception where an offender can be charged only if 18 years of age or older. However in that case, it is possible for both minors to be charged as "unruly" if brought to court {§ 2151.022 (A) }.
2907.04 Unlawful sexual conduct with minor.
(A) No person who is eighteen years of age or older shall engage in sexual conduct with another, who is not the spouse of the offender, when the offender knows the other person is thirteen years of age or older but less than sixteen years of age, or the offender is reckless in that regard. {§ 2907.04}.
However, the preceding statute, Section 2907.03, specifies that sexual conduct between anyone under 18 and a teacher, administrator, or coach of the school they attend, a cleric, or other person in authority, is punishable as a felony of the third degree.
2907.03 Sexual battery.
(A) No person shall engage in sexual conduct with another, not the spouse of the offender, when any of the following apply:
(5) The offender is the other person’s natural or adoptive parent, or a stepparent, or guardian, custodian, or person in loco parentis of the other person.
(7) The offender is a teacher, administrator, coach, or other person in authority employed by or serving in a school for which the state board of education prescribes minimum standards pursuant to division (D) of section 3301.07 of the Revised Code, the other person is enrolled in or attends that school, and the offender is not enrolled in and does not attend that school.
(8) The other person is a minor, the offender is a teacher, administrator, coach, or other person in authority employed by or serving in an institution of higher education, and the other person is enrolled in or attends that institution.
(9) The other person is a minor, and the offender is the other person’s athletic or other type of coach, is the other person’s instructor, is the leader of a scouting troop of which the other person is a member, or is a person with temporary or occasional disciplinary control over the other person.
(12) The other person is a minor, the offender is a cleric, and the other person is a member of, or attends, the church or congregation served by the cleric."
I think a case could be made for sexual misconduct by Mazzola as he did have authority over the 17 year old.
