Again, this is a false narrative. The scholarships are NOT binding for 4 years. They are renewed annually, and despite what you want to believe, SA’s are processed and left with no scholarship. The 2,000 players remaining in the Portal is evidence of that.
Roughly 60-65% of the players currently in the Portal with no home are not in the Portal because they are looking for greener pastures.
The roughly 1-2% that get the HL’s when leaving already have a “home” before officially placing their name in the Portal.
Also, if you really think a “brand” means more than a star athlete at 98% of the schools, I don’t know what to tell you. GT had the “brand” for hoops under Bobby C and Hewitt, like Bama did under numerous coaches and most recently Saban. When programs struggle or are just the average P4 school, that “brand” is not bringing in the $$$. Texas, tOSU, Michigan, Oregon, USC, PSU, Alabama, etc are the exceptions to the rule.
