For the majority of high major basketball players, academics matter, but only up to a certain point. And that point is generally somewhat low (relative to non-athletes such as ourselves), even for really smart athletes like Okoro. Program rankings to athletes are generally less important than whether the school has a curriculum designed to fit well with a basketball schedule. Rankings are less important than the overall academic support, like tutor programs. This list could go on and on.
The debate about which school has the better computer science program and stuff like that is just silly. It's a factor, but might as well be a non-factor because of how low it is on the list. It's a factor as in "oh good, you offer computer science here"... beyond that, what top athletes value for academics is largely the surrounding/supporting stuff. Point being, rankings are far more important to those picking a school primarily for academics vs. secondarily (i.e. those with professional basketball aspirations).
