So often, when you reference the big numbers of a pitcher from baseball's past, you are dealing with results that have no modern relevance. They certainly have little use as a signpost for what some present-day hurler might do. Things have changed too much.
There are some obvious examples of that which come up in a records-never-to-be-broken debate, like Cy Young's 511 wins or 749 complete games, figures compiled during baseball's mythical-sounding past. You don't even have to go back that far. The post-World War II record for innings pitched in a season was set less than 50 years ago: Wilbur Wood threw 376u2154 innings in 1972, edging out the 376 mark set the season before by Mickey Lolich.
