The main reason to attend a high school sports combine is to get measurable information about your skills. Verified statistics are important for your player profile, so getting timed in the 40-yard dash or shuttle run, or having your vertical jump measured at a combine can be beneficial. Verified combine results posted on a profile page from a trusted third party like Scout Kings can be extremely valuable to college football coaches.
Combines can provide good, measurable information about your athletic ability, which can help you see how you measure up against other potential college recruits. Knowing what you need to improve on can help you when competing against other athletes for scholarships.
