It should not be the sole determining factor, on that we can agree. But if your statement goes further than that, and that it shouldn't even be one of the factors, then mind explaining what aspect of bWAR for pitchers makes you feel that? bWAR for pitchers has a black box feel that often doesn't pass the smell test. Look at Chacin's numbers and Arrieta's numbers and explain why Arrieta is a 3.3 bWAR and Chacin is 1.9 bWAR. Chacin has better numbers for Games, IP, ERA, FIP, WHIP, K9, H9, HR9, and WP. Arrieta leads only in BB9, K/BB and HBP. For batters in bWAR, look at last year's stats and explain why Sogard had a better bWAR than Braun (1.9 vs 1.2). Also the fact that there is a bWAR and an fWAR that can be significantly different makes the whole concept of a WAR stat seem less reliable. Even ignoring WAR, DeGrom's stats are impressive and worth consideration of a Cy Young award. Given that we are in the era of the reliever, it's impossible for a pitcher on a bad team to have a '72 Steve Carlton record.
