re: Since the transfer portal is out of control, what rule change would you make if you could?

Every athlete in every sport is contracted. They receive a full ride for room, board and meals. The contract can be negotiated for 1 to 5 years. Any NIL money can be negotiated into that contract. If the contract is broken by either side then it's treated like any other contract with appropriate penalties. Athletes are representatives of the school and should be treated as contract employees.

If all of this happens then the portal crap is instantly much more under control in every sport. Athletes can still get paid. They just have to negotiate it into the contract.
