Lanardo "The Pain Server" Tyner has a good record but has fought limited competition. Arnaoutis is a big step up for him. I'll be pulling for Tyner since he's a Detroit native, but if I had to bet I'd probably bet on Mike.
Yes, Tyner is physically strong, brings the fight to his opponents, and has decent power in both hands. Not a great technical fighter though. He's struggled against lower level opposition too, so Arnaoutis will probably beat him.
