Para entradas com menos de 28 jogadas, com 45 gols contra e 1 de 33 pontos, qual é a média do sorteio?
CREATE TABLE table_name_45 (drawn INTEGER, played VARCHAR, points_1 VARCHAR, goals_against VARCHAR)
SELECT AVG(drawn) FROM table_name_45 WHERE points_1 = "33" AND goals_against = 45 AND played < 28
