How many percent of points were scored by NBA players who belonged to 'LAL' team and had performed steals movement.
NBA refers to lgID = 'NBA'; 'LAL' team refers to tmID = 'LAL'; performed steals movement refers to steals > 0; percent = divide(count(playerID where steals > 0), count(playerID)) where lgID = 'NBA' and tmID = 'LAL' * 100%
SELECT CAST(SUM(IIF(T2.steals IS NOT NULL AND T1.tmID = 'LAL', 1, 0)) AS REAL) * 100 / COUNT(T1.tmID) FROM teams AS T1 INNER JOIN players_teams AS T2 ON T1.tmID = T2.tmID AND T1.year = T2.year
