This from a Masters Thesis which studied the factors driving school selection:
"In the end, I was only able to confirm much of what was already believed to be the secret to successful recruiting: winning. Previous winning percentage, both in the last two years and all-time, along with bowl victories, are major factors in the quality of a recruiting class.
On top of winning, the schools that were good at recruiting in the past tend to be good at recruiting in the future, and schools that win also tend to have higher average attendances and better recruiting
classes. However, the most interesting information about this study was the insight into the validity of what stakeholders seem to think impacted recruiting. Some of the most striking revelations were not necessarily what factors were shown to affect recruiting, but rather what factors were shown to not affect recruiting, despite the anecdotal evidence espoused by student-athletes, coaches, and the media. Academic quality of the institution, thought to be a deciding factor for student-athletes, was shown not to be a significant factor in any of the models. The same can be said for apparel affiliation, NCAA violations, athletic department expenses, and type of offense. Despite what is thought to be impactful on student-athlete college choice, none of these factors were shown to have an effect on the quality of a school’s recruiting class."
