Table schema:
CREATE TABLE table_name_64 (byes INTEGER, against VARCHAR, wins VARCHAR, benalla_dfl VARCHAR)

Question: What is the highest value for Byes, when Wins is less than 16, when Benalla DFL is "Swanpool", and when Against is less than 2177?
SQL: SELECT MAX(byes) FROM table_name_64 WHERE wins < 16 AND benalla_dfl = "swanpool" AND against < 2177
