So Musselman and Oats—despite practically having the same resumes as Underwood—are higher on Texas’ list than Underwood (in a year in which Underwood had the most successful overall season) because Underwood lost to Loyola.
There is some danger in overvaluing tourney performances. John Groce, for example. All the HOFers you brought up have had worse tourney losses than Loyola, including Pitino. But their overall bodies of work are tremendous, which is why you keep recommending them.
Also why would Cal leave the bluest blue blood for any other reason than his seat was getting warm and/or needed a change of scenery? He’s already the highest paid coach in CBB at over 8 million a year.
