Outside of the states of Kentucky, North Carolina and Indiana no one gives a rip about college basketball in any meaningful numbers.
I remember being in Blacksburg VA, mid 2000s, on spring break. My buddy from HS went to Va Tech and we went out there to party for a week. Lol I know I know "who goes to Blacksburg on spring break." Hokies were at Cameroon Indoor and beat Duke. We were at some big bar, packed, TVs everywhere with the game on. Me and my other fellow UK buddy and about 5 Hokies were actually watching and cared when VT won. No one else there, all students, gave a single ****.
So when they go on about nationally....youre talking about bandwagon CBB "fans" who tune in and only began seeing whats going in CBB for March gambling purposes, usually people in pro markets. They don't "care" at all. Theyve been told ad nauseum it's a big game, so they tune in so they can take part in something theyve been told is part of the sports cultural lexicon.
Its like saying these people's opinions matter on horse racing because they watched the Kentucky Derby.
