    【Question】
    What division did the team coached by the winner of the 1977 NBA Coach of the Year award play in in 1976? "NBA Coach of the Year" is the award; in 1977 refers to year = 1977; in 1976 refers to year = 1976; division refers to divisionID

    【Evidence】
    "NBA Coach of the Year" is the award; in 1977 refers to year = 1977; in 1976 refers to year = 1976; division refers to divisionID

    Please read and understand the database schema carefully, and generate an executable SQL based on the user's question and evidence. 

SQL: SELECT DISTINCT T3.divID FROM awards_coaches AS T1 INNER JOIN coaches AS T2 ON T1.coachID = T2.coachID INNER JOIN teams AS T3 ON T2.tmID = T3.tmID WHERE T1.year = 1977 AND T1.award = 'NBA Coach of the Year' AND T3.year = 1976
