I wanted to start with Kevin Brown because he’s a special case (at least on this list). Brown appeared on the 2011 Hall of Fame ballot and received just 2.1% of the vote. Meanwhile, we’ve watched Jack Morris—an inferior pitcher—climb all the way to 66.7% (and counting).
...Brown had eight 4+ WAR seasons, tying him with David Cone. Brown, Cone, Frank Viola, Dave Stieb, and Nap Rucker are all tied for the most 6+ WAR seasons (four). Out of curiosity, I checked 8+ WAR seasons. Brown is one of several pitchers with one. Wilbur Wood, Sam McDowell, and Eddie Cicotte (who is not eligible) have two.
For the ERA+ lists, I only looked at seasons that qualified for the ERA title. Brown has seven seasons of 125 or better, tying him with Cone, Tommy Bridges, and Hippo Vaughn. Crank it up to 150 and Brown is all alone with five. Cicotte and Smokey Joe Wood are behind him with four. I was curious where Cone placed—he’s tied for sixth with two such seasons. For fun, I kicked it up to 175. Brown has one such season. Cicotte and Wood have two each.
Among pitchers, Brown ranks 34th all time with 64.8 WAR. By wWAR, Brown ranks 41st all time (95.9), just behind Sandy Koufax, Hal Newhouser, and Jim Bunning. Eight of the pitchers ahead of him aren’t even eligible for the Hall of Fame yet, so that puts him at 33rd among those eligible. 32 of them are in the Hall of Fame (Bob Caruthers is not). Brown even ranks ahead of 29 starting pitchers who are already in the Hall of Fame (including Mordecai Brown, Dazzy Vance, Don Sutton, and Whitey Ford).
