I perhaps wouldn’t mind a potential backstage role but have zero interest in that guy as a talent.
If by "backstage role" you mean janitor, then that's fine.
Other than that, I wouldn't want Sami booking, producing, or influencing my younger talent in any way backstage.
Since Sami is still a popular garbage wrestler & he has a real-world connection to Moxley, I'd give them a short program (or tag team run) to see if they could draw money. Other than bleeding & better-than-average promos, I don't see the value in hiring Sami Callihan.
That being said, if Shad Khan's purse is still open, I can't blame creh for getting an easy payday.
