portal can backfire sometimes. Louisville was slipping so they fired Chris Mack mid-season in 21-22. New coach Kenny Payne didn't assemble a great team and first season was awful especially playing in a good conference.
It is hard to fathom that they can be so bad when they have such a strong passionate fanbase. But just like a basketball team can turn things around quick from year-to-year because there are only 5 on the court, a basketball team can also nose-dive quick from one season to next.
