Actually alixana, the HOF does have a veterans committee, which is used to elect players that might have been overlooked during their original eligibility. And players do make up part of that committee. But Morris is going to have to wait a long time before he becomes eligible for the committee.
And Murphy's case for the HOF isn't anywhere near as good as Morris'. While Dale was just about the best player in MLB for a couple of years, his years of excellence were actually pretty short. He also doesn't have any post-season heroics, wheras Morris is one of the better big game pitchers of all time.
And while some players have had contentious relationships with the media over the years, for the most part, the writers would elect Satan himself if he had the numbers. Put it this way, had Bonds retired after the 1998 season before his PED use started, he gets in a walk, no matter what people thought of him as a person.
Finally, over the past 10 years a lot of the writers have embraced advanced metrics stats. While it's not universally used, it's incorrect to think that they aren't being used. What you see is most of the newer, younger writers who are using them in their assessment process. But next year, you don't need any stats to elect Greg Maddux, you just know.
