Given how much Yormark has leaned into New York City as an important market, and his obvious connections there, along with his push for the Big 12 to gain national appeal, I expect that he will call St. John’s to see if they will join the league as well. (Either alone as a team #14, or perhaps as a group with some combination of two of UConn, Villanova, Georgetown.)
St. John’s home games against Gonzaga, Kansas, Baylor, whoever else is a top Big 12 team at that time would be marketed as major New York sporting events at MSG or Barclays Center.
