Analysis: Blyleven is in the ball park in Winning Percentage with all of them. His ERA+ is higher than all of them. His Strikeouts Per Nine Innings is higher than all of them. He had more shutouts then all of them. His Walks per Nine Innings and WHIP are right there with them. Only Jenkins had a better Strikeout to Walk Ratio. Fergie Jenkins had a superior stretch of dominance, but less total wins. His Complete Games are in the same ballpark.
Some would say that Sutton and those would be marginal Hall of Famers. This writer says that they are in the Hall of Fame and as such are benchmarks. Blyleven deserves a place in the Hall of Fame. If those guys are in there, he should be in there.
