as a historical ceiling. No one is arguing what has been accomplished the past decade during the regular season (though citing 20 win seasons as many do rings hollow unless the goal is to be a regular season lion and a tournament mouse). What matters is what has been done post season: conference titles and NCAA wins. In those most important measurable regards, I would say it's not as clear-cut as you want it to appear.
There's a difference between the goals of being the best vs not being the worst.
