We all know that having a great starting pitcher on the mound gives you a better shot to win that game.
From 93-98' Greg Maddux was on good Braves teams. He finished 1st,1st,1st,4th,2nd,5th in the Cy Young and a combined 2.15 ERA in the 6 years. The Braves record was 125-66 in his starts.
So they won 65.4% of the time he started. As good as Maddux was, with those #s, the Braves should have won more than that when he started. But that is how baseball works sometimes. A pitcher W/L record is an overrated stat...but I will say that the Braves were only 18-24 in the games where Maddux was not involved in the decision. Our Royals have had a good record when our starting pitcher isn't involved in the decision (not shocking having the tremendous Pen we have)
