The Zags have entered talks with multiple leagues throughout the past year as it explores options
Seems like it could happen. The Big 12 propogandists will view this as some major money move but the B12 source said its not a financial gamechanger. Obviously. As regular season college basketball isn't very valuable. They'd only bring enough money to pay them and keep everyone else at the same rate. So maybe $5 million-$10 million per year for Gonzaga. That's my guess.
I do wonder though if they are using this as leverage to get into the Pac 12 or Big East.
