I didn’t think he was a Hall of Famer back in 2018 and I was on the fence on him last year but I have changed my mind on him.
The career WHIP of 0.998 is a big thing plus his 11.9 career K/9 rate compared to the 3.0 BB/9 rate. Also, the career ERA+ of 187 and having five seasons with at least 66 appearances with an ERA+ of 196 or better makes him a Hall of Famer to me.
His postseason numbers are very alarming but it is a small sample size (11 2/3 IP).
Like Larry Walker, he has largely been discounted because the “Coors” narrative. However, from 1998 to 2005, he was one of the most dominant players in baseball even with the park adjustments. In that span, he had an OPS+ of 149. He also had seven season with a bWAR of 4.5 or better and even on the back end of his career, he was still a good defender with 30 bDRS from 2003 to the end of his career (the DRS stat only goes back to 2003).
Overall, I don’t think he has as strong of a case as Walker does but that doesn’t negate the fact that he is a Hall of Famer.
