Big West Tournament There are a bunch of sad little gyms in the league, so I wouldn't rotate to every campus.
Bren Center is a nice 5,000 arena, it would look great on tv if packed. I haven't been there in 20 years but I remember it as being nice.
Irvine is very close to 3 Big West campuses and I'm guessing 7 schools are 2 hours or less away.
It's near the beach, Disneyland, airport, hotels.
Yes it's very far from Davis and Hawaii but guessing way more Davis and Hawaii fans would show up in Irvine than Henderson, NV.
