It was definitely a different time for pitching in the early 1900's. Young pitched well over 350 innings in each of his first four years. He also compiled a lot of wins for the young team. He won 30 games twice and 20 games four more times. He lead the league in wins three times, losses once, ERA once, strikeouts once, and several other pitching categories in his time with Boston.
While Cy Young's career would have likely gotten him into the Hall of Fame without his time with Boston, that time certainly helped in getting him into Cooperstown.
