List the positions of players whose average number of points scored by that position is larger than 20, compare the number of positions, and could you rank in descending by the X?
SELECT Position, COUNT(Position) FROM player GROUP BY Position HAVING AVG(Points) >= 20 ORDER BY Position DESC
SELECT "Position", COUNT("Position") FROM "player" GROUP BY "Position" HAVING AVG("Points") >= 20 ORDER BY "Position" DESC
