This list includes all titles won this school year, minus baseball, which is still ongoing.
The number in parentheses shows how many sports at that school have won national titles. I didn't bother with schools that had 0 or 1 titles, because, well, it's pretty obvious there.
So a school like Oklahoma State has 45 titles, but all came in just 5 sports (specifically their 32 in men's wrestling).
Just keep this in mind next time someone tries to say East Coast schools are better as a whole.
