What is the percentage of players who attended Auburn University and won an "All-Defensive Second Team" award?
Auburn University refers to college = 'Auburn'; won an "All-Defensive Second Team" award refers to award = 'All-Defensive Second Team'; percentage = divide(count(playerID where award = 'All-Defensive Second Team'), count(playerID)) where college = 'Auburn' * 100%
SELECT CAST(SUM(CASE WHEN T2.award = 'All-Defensive Second Team' THEN 1 ELSE 0 END) AS REAL) * 100 / COUNT(*) FROM players AS T1 INNER JOIN awards_players AS T2 ON T1.playerID = T2.playerID WHERE T1.college = 'Auburn'
