Bert Blyleven was the consensus "best pitcher not in the Hall" for so long, I'm curious who the next one will be. Honestly, with all of our Bert support, we probably let the next best slip by just this season. And that's Kevin Brown. Rick Reuschel leads in WAR, but Brown passes him via wWAR. The wWAR list also shows some 1800s pitchers leapfrogging Brown, but much of that is due to pitcher usage of the time. However, if you count those 1800s pitchers you get Jim McCormick. Who's after the 1800s pitchers, Brown, and Reuschel? That'd be Luis Tiant. Then, David Cone.
Who do I believe it is? I'm not really sure. That's a great question.
