Schema: CREATE TABLE table_name_45 (drawn INTEGER, played VARCHAR, points_1 VARCHAR, goals_against VARCHAR)
Question: For entries with fewer than 28 played, with 45 goals against and points 1 of 33, what is the average drawn?
SQL: SELECT AVG(drawn) FROM table_name_45 WHERE points_1 = "33" AND goals_against = 45 AND played < 28
