What a guy
Just how good has Cubs' pitcher Greg Maddux been over his career? Top ten of all time? Possibly. Look at it this way: he is the only guy to win 15 games 17 years in a row. Pretty amazing when you consider he is going up against those guys from the dead ball era that routinely got over 25 wins in a year. His closest competitor in that streak is the guy they named the annual pitching award after.
On the baseball reference sit he is credited with two of the top ten adjusted season ERA's of all time. All of that with a fastball under 90 mph. What a guy.
