You are correct... from the ncaa men's soccer handbook.
the campus of one of the participating institutions.
An evaluation will be made of institutional facilities to determine if they are
acceptable for championship play. Selection of host sites will be based partly on the
quality of the playing facility. A facility evaluation form will be made available on the
NCAA website to the directors of athletics of all institutions and will be one of the
tools used in making this determination. Institutions interested in hosting are to submit
the form online by the indicated deadline. Institutions submitting proposed budgets
for preliminary rounds must have played the majority of their home games at the site
listed on the facility evaluation form. Institutions with inadequate playing surfaces
(e.g., inadequate artificial surface, minimum dimensions, etc.) may request a waiver
of the policy.
Site Selection. The site selection criteria for the Division I men’s soccer championship
are as follows (see Appendixes F and G):
60 percent Committee ranking
40 percent (1) Facility—
Quality of field surface (60 percent)
Evaluation of facility (30 percent)
Game management (10 percent)
So, basically the ncaa chooses. We'll see how that goes.
Based upon this criteria, Akron has a GREAT chance of hosting this sweet 16 game (Defending Nat'l Champs!).
