Table schema:
CREATE TABLE table_name_84 (gain INTEGER, long VARCHAR, name VARCHAR, loss VARCHAR, avg_g VARCHAR)

Question: Which Gain is the lowest one that has a Loss larger than 2, and an Avg/G larger than -6, and a Name of sheehan, tyler, and a Long larger than 11?
SQL: SELECT MIN(gain) FROM table_name_84 WHERE loss > 2 AND avg_g > -6 AND name = "sheehan, tyler" AND long > 11
