My assumption is a large chunk of the roster gets the $1K minimum.Rocco supposedly made $1.5 million last year. Stars get money. Unproven lower rated high schooler kids aren’t getting what you think.
My assumption is also that many recruits who get more aren’t renewed at the same level unless they pan out on campus.
These are ignorant assumptions, but it doesn’t sound crazy to think a recruit at a high dollar position could get $200k at ISU and not be as attractive as a transfer vying for the same spot in the February signing period for most P4 schools.
