Alabama basketball coach, Nate Oats is like all mid-major and high-major coaches in one respect. Winning requires ballers to execute any system. Those ‘ballers’ may end up having been lesser-valued recruits, but for any program to consistently win, it needs some Top 100 recruits.
Yes, there are exceptions, though the exceptions most often come from a hot team for a season. Some basketball coaches do more with less, developing a group of lower-valued players, into a big-winning team for a few seasons.
But the norm is it takes elite talent to win. That is why Duke and Kentucky and other college basketball bluebloods win with such frequency.
