The Big 12 is the only power conference that has yet to win a playoff game
The Pac 12 seems to get better players than both the ACC and the Big 12 according to the NFL draft.
There is only 1 week in the first 7 weeks this year where a matchup between two teams from the “new” Big 12 had a better rating than the top rated game featuring 2 teams from the Pac 12.
In the last NCAA basketball tournament the Pac 12 had twice as many teams in the Sweet 16 than any other conference. They had 3 teams in the elite 8. I wouldn’t call that a bad trend.
