CREATE TABLE table_name_88 (total NUMBER, play_offs VARCHAR2, league VARCHAR2, player VARCHAR2)

What mean total had a league number of 18, Richard Logan as a player, and a play-offs number smaller than 1?
SELECT AVG(total) FROM table_name_88 WHERE league = 18 AND player = "richard logan" AND play_offs < 1
SELECT AVG("total") FROM "table_name_88" WHERE "league" = 18 AND "play_offs" < 1 AND "player" = "richard logan"
