Question: Give the name of the league had the most matches end as draw in the 2016 season?
Evidence: most matches end as draw refers to MAX(SUM(home_team_goal = away_team_goal)); 2016 season refers to season = '2015/2016';

SQL:
SELECT t2.name FROM Match AS t1 INNER JOIN League AS t2 ON t1.league_id = t2.id WHERE t1.season = '2015/2016' AND t1.home_team_goal = t1.away_team_goal GROUP BY t2.name ORDER BY COUNT(t1.id) DESC LIMIT 1
