Trying to figure out recruiting success based solely on offers is a bit of a fool’s errand. There is no accountability system out there to verify an offer. Every recruiting service has stories of schools texting/calling an outlet to say we didn’t actually offer that kid. But coaches can’t say anything publicly. And even if they did say the words “we’re offering you a scholarship”, there’s no way to verify that an offer is still valid 1, 3, or 6 months later.
That’s why going off of official visitors is a bit more of a reliable method even if it lowers your sample sizes.
