I think part of any HOF discussion should be how the player was regarded, in terms of tracking towards the HOF, during his playing days. Not only by his peers, but also by the people covering the sport.
What BL refuses to acknowledge, or just willfully discredits because he can ONLY see things through the lens of his precious "new stats", is that players like Catfish Hunter were thought of as sure-fire HOFers at some point during the course of and for the remainder of their active careers.
I don't think Trammell or Morris were ever thought of that way during their active careers, except by the "homer" fans. They were regarded as very good All-Star caliber players, but you never got the feeling while watching them play that "this guy is going to be in the Hall of Fame someday".
Even in today's game, there's probably only a handful of guys who fit that description. Guys towards the end of great careers, or at or approaching the peak of an already impressive career. Kershaw and Trout come to mind for the latter (though neither one has the required service time to even be eligible, yet).
