I don’t know of any specific cases, but any football player getting a full COA plus a stipend (or Pell grant), plus insurance would fall into the big tax picture.
A Stanford football player would be have to claim $16,400 for room and board, $5200 for health insurance, and ~$6000 as a subsidy, so $27,600. Standard deduction of $12k and that leave $15,500 as taxable. Ouch.
