Five recruiting battle wins for NU

I have an article idea for you. I don't have the time or resurch skills to do it, but have been wondering about this issue. How many of the recruits at the end of the recruting cycles were drafted to the NFL after their senior season in college football per each catigory (5*, 4*'s and 3* rankings). For example: do 100% of the 5* recruits make it to the NFL? How do 3* kids compare in successfulness. I am using an NFL draft as an indication of how successful a recruit was durring his college career. My hypothisis is that Seniors in Highschool have matured at differant rates. 5* recruits may actually be simply early maturing kids and likewise a 5* doesn't always have the determination and work ethic to be successful at the next level. Conversly a 3* recruit could be a late bloomer and have the other factors necessary to be very successful for their college. Put more simply, what % of 5* kids are successful in College football compared to 4* & 3*. I am sure this resurch has been done but I would find an article on the subject very interesting.
