I mean sure that's fine. I just don't think all of a sudden he'll get a big spot somewhere and I don't necessarily think he should. I love the shit out of that man, but...I'm not sure what you're even arguing against.
I get that you're worried Rusev will flop outside of the WWE but thats not a given.
Rusev is super solid and has put in matches people like. I think he deserves a chance elsewhere to fail or succeed if he feels like it.
WWE don't really have a place for Rusev right now, I don't see the problem with him trying to re-establish himself somewhere new where they could use more heavyweights like him.
