Speed's pretty but what counts most is control. Look at Ryan and Koufax. Early on, with control issues they were marginal W/L which is the only measure of a pitcher's effectiveness. Cut out the walks.

It is interesting that today's pitchers are often viewed by the chronologically gifted fan as "weak", being limited to maybe 100-120 pitches on a good day. While not arguing that too many pitches may destroy an arm, K and those guys were going complete games at or below 100. Too many wasted pitches, some of which may be the responsibility of the Man in Blue.
