"There are additional expansion options beyond UConn, some of which don’t play football. The primary candidate outside the football realm is West Coast Conference basketball power Gonzaga, which would give the Big 12 a school in all four time zones and a coast-to-coast presence.
St. John’s, in Yormark’s hometown of New York, also has been floated as a possibility. Yormark has been clear that basketball is key, adding that basketball is “a catalyst for a lot of things moving forward,” including “international expansion.” Teams that advance in the NCAA basketball tournament also earn more money for their conferences—each round means more cash in both the school’s and conference’s pockets. The Zags have made eight straight Sweet 16s and 24 straight NCAA tournament appearances."
It's been discussed before, but mostly stemming from an anonymous twitter account or speculative opinion articles. This is another Pat Forde article with sources explicitly naming St. John's. Very interesting.
