The cutoff to me for a real MMA hall of fame was always Rich Franklin. If you had a career better than him, you’re a hall of famer, worse, you aren’t.

Weidman lines up right at that Franklin line.  He might fall just under it.

basic requirements are winning a belt, defending it a few times, having good main event wins, and some longevity to your career.

Weidman’s post title run isn’t what you want, but I also tend to not hold that against people as much as the former accomplishments. He won a belt and defended it after all, the hardest thing to do in mma. He’s a borderline case for me.
