Most of the APR requirements do not kick in until the end of a student athlete's sophomore year when he must be 40% towards obtaining his degree. So the one and done players at UK, who are required to have 24 total credit hours (12 of which can be in remedial classes) after their first year, for the most part, easily are within the broad guidelines. Every major program has their players in for summer sessions that provide up to 12 credit hours. Then each player will need to stay eligible during the season (fall semester) while passing an additional 12 hours.
Coach Cal doesn't get into trouble with the APR until a player who was expecting to leave after one year, sticks around longer.
