Depends if Aspinal shoots right away or not
He submits Gane round 1 if he does but he could try for a ko and drag it longer.
If i was the UFC i would promote Tom as MMA's Mike Tyson. Keep him active (4 fights a year atleast) and the 1 round finishes will do the promotion for him. People wouldn't care about "if this guy is a real challenge or not" since tbh there is none, they'll just enjoy watching him finish another bum.
