Pretty much what I expected. Without looking up the history of National Championships I thought maybe Men's Volleyball and Women's Soccer might make the list.
While PSU Mens vball has done very well (we were the first team East of the Mississippi to win an NCAA title) it is still a sport dominated by west coast teams. I think Hawaii/California account for the last 6 straight titles.
Ohio State, Penn State, Loyola have some scattered championships, but it's been a lot of UCLA, Pepperdine, Long Beach St, UC Irvine, etc over the years.
