Who was the coach for the team which had the most bench minors penalty in 2003？
Coach of the team refers to firstName+lastName; 2003 refers to the year


SELECT DISTINCT T3.firstName, T3.lastName FROM Teams AS T1 INNER JOIN Coaches AS T2 ON T1.tmID = T2.tmID AND T1.year = T2.year INNER JOIN Master AS T3 ON T2.coachID = T3.coachID WHERE T1.year = '2003' GROUP BY T3.firstName, T3.lastName ORDER BY SUM(T1.BenchMinor) DESC LIMIT 1
