Table schema:
CREATE TABLE table_name_86 (points INTEGER, player VARCHAR, extra_points VARCHAR, field_goals VARCHAR, touchdowns VARCHAR)

Question: While Duncan Thompson played, how many points did he have where there were 0 field goals, 0 extra points, and more than 9 touchdowns?
SQL: SELECT AVG(points) FROM table_name_86 WHERE field_goals = 0 AND touchdowns > 9 AND extra_points = 0 AND player = "duncan thompson"
