The recruiting services rankings are just entertainment for college football fans. Some elite QBs are just obvious like Trevor Lawrence, but those guys only come along every 5-7 years, most years there is not an elite QB recruit and it's just good potential based on reputation and who's recruiting who, but the services need to fill out their rankings to entertain us and get our money so they just assign stars for their customers.
There was no Trevor Lawrence recruit last year and there's no elite recruit this year either, they're all projects. This is why you have to recruit good HS projects every year and not take a flyer on guys that don't pass the eye test just to take one.
