Just because someone is in the portal doesn't mean they're leaving. For some it's a way to test interest.
For a player like Sanders, there will be plenty of offers from FCS and G5. If it's interested in earning a free master's degree + playing another year of football, he could go to a place like Georgetown or Villanova and do well.
Speaking of Georgetown, do online programs count towards academic eligibility? For example, Georgetown has the online School of Continuing Studies, in which there's an MPS (Masters of Professional Studies) in Sports Management (
