I don't want to fight. However, your basic premise is something very very rudimentary. Everybody has known for years, decades that a pitcher can't completely control W/L record, yet it was perhaps THE most important factor in a pitching winning Cy Young (prior to the emergence of closers). It doesn't take a rocket scientist to deduce some pitchers have very tough luck in trying to rack up wins, instead get no decisions. Yet again ... forever it was THE bench mark for starters along with ERA of course.
Bruce Sutter won Cy Young in 1979. Before that ... all W/L and ERA. McCormick 22-10, 2.85; Gibson 22-9, 1.12; Seaver 25-7, 2.21; Gibson 23-7, 3.12; Fergie 24-13, 2.77; Carlton 27-10, 1.98; Seaver 19-10, 2.08; Marshall 15.21 withi 21 saves, 2.42; Seaver 22-9, 2.38; Jones 22-14, 2.74; Carlton 23-10, 2.64; Gaylord Perry 21-6, 2.73; then Sutter.
Then after Sutter and 37 saves it was all W/L and era cept for relievers: carlton 24-9, 2.34; Fernando V 13-7, 2.48 (strike); Carlton 23-11, 3.11; John Denny 19-6, 2.37; Sutcliffe 16-1, 2.69; Gooden 24-4, 1.53; Mike Scott 18-10, 2.22; Bedrosian 40 saves; Hershiser 23-8, 2.26; Davis 44 saves; Drabek 22-6, 2.76; Glavine 20-11, 2.55; Maddux the next four years all based on wins and era; Smoltz 24-8, 2.94; Pedro 17-8 1.90; Glavine 20-6, 2.47; Randy Johnson next four years all wins/losses and era based; gagne 55 saves in 2003; then clemens, carpenter, webb, peavy, lincecum twice in a row; halladay, kershaw, dickey, kershaw twice in a row; arrieta, scherzer twice all based on WL and era. last year deGrom more on the advanced stats. 10-9, 1.70
I can do the AL pitchers next if you wish. Even last year's snell at 21-5, 1.89 was traditional W/L and era. In 2010, felix hernandez won 13 and lost 12 so that was ignored cause of his era and strikeouts and he won it; Aside from that, all W/L and ERA cept for Eck's 51 saves; willie hernandez's 32 saves; rollie fingers 28 and sparky lyle's 26. Aside from relievers and Felix hernandez, all cy Young winners based on W/L, ERA.
Seems to me we now know why Stoney mentions wins and losses so much, folks.
