I've checked Otto Wallins boxing skills and watch some of his fights and unless Tyson is on a sloppy condition, I don't think he'll have a chance to Beat Tyson, he is not on a class like Ruiz to beat a fighter like Tyson, and I don't think it's a good tune fight for the coming Wilder match.
I was searching when will be the next fight between Tyson Fury and Otto Wallins and found that they will meet on September 14 in Las Vegas. This is going to be a thriller in T-Mobile Arena. Whatever other people suggests and predicts, i still believe that Tyson Fury is the favorite because he has beaten Wladimir Klitschko and is more famous than Otto Wallin.
