Playing football in College is not as easy as it was in High School. There are many rules and steps you must take as an athlete to make it happen. According to NCAA only 7.1% of high school athletes move on to the college level and only 2.8% make it to Division 1, 1.8% Division 2, and 2.5% play for Division 3 schools.
The first hurdle you must clear is academic eligibility, for Division 1 you must have completed 16 core classes, have a 2.3 cumulative, and SAT combined score or ACT sum score matching your core-course GPA on the Division I sliding scale, which balances your test score and core-course GPA.
What you need to know up front is that there are also factors that can prevent you from playing that you can not control. Your height will prevent or allow you to obtain a certain division.
If you want to play ball in college there is a place for you, but you have to do your research to see where you qualify to play.
