I really want to see Gustaf fight Jones. Jones is beating great fighters but he has not fought a young lion like himself, with size to match, since Bader. And Bader is hardly a lion.
Shogun is on the decline but he is a born-to-fight fighter. Meaning no matter what shape he's in, he's a handful. Unlikely to hold the belt again, I don't know how much he wants it, but he can certainly put other guys' dreams on pause.
I really want to include Gustaf in my betting but he's going to bang with Shogun... I can't risk a parlay on that.
