This conversation has been about who is a good candidate for Meritorious Service, not Greatest Player.
There is something to be said about his impact on the game. He discovered and exploited flaws in racking advancements in the game to a degree the rules needed to be changed. That’s not nothing.
But if you look at his actual achievements. No world championships. He had a US Open win with a soft break asterisk. But if you want to hoist him up in the rafters with the likes of Mosconi, Sigel, Strickland, Varner, Reyes, Pagalayan, Appleton, SVB, etc. his accomplishments are far short.
There are plenty of players (some not yet eligible yet by age) the clearly demonstrate career achievements that are just over the bar worthy of the HoF that Deuel hasn’t matched, e.g. Filler, Ouschan, FSR, Biado, Chang, etc.
When you look at resumes really closely, there’s names even stronger than his that you could argue haven’t done enough yet to make their case when they are eligible. Shaw is a great example. No world championships. His big titles are US Open, Intl Open (x2), Hanoi, and DCC Bigfoot. As respectable as they are the SBEs and Turning Stones don’t really make the case. His Mosconi Cup MVPs probably will nudge him over the bar. But a world championship would really seal the deal for him. And my point isn’t to debate Jayson but just to illustrate how a player of his caliber can be borderline and then you look back on a Deuel and start noticing a pretty wide gap.
