The NCAA minimum is 7. It’s in the rules. You can view them by downloading the file.
Pac 12 is also 7 and no mention of gk, but like I said I’m sure there’s a behind the scenes agreement that it wouldn’t be less than 14/15 or whatever. But officially it’s 7. That will never ever happen.
The rules to start a match is 7. Its 3.1 I think under the NCAA rules. Just like it’s 11 for football and 5 for hoops (presumably; not sure if there is an odd rule about starting with 4). But the Pac-12 had its own rules for football and has its own rules for basketball about numbers or players dressed (and the scholarship status of those players) that go beyond what’s required on the field to blow the whistle. The pac published those. I’d expect that something like that exists for soccer - not just an behind the scenes agreement but an analogous policy. I’d expect that for many other of the team sports. And I’d guess it will be published at some point.
