Gane is just way better in all aspects of the game if compared with Tuivasa. But I'm not saying Tuivasa can't win. He can, esp with Gane having the tendency to dart in with his shots at times. It opens opportunities for Tuivasa to get in the clinch and do those elbows like he did to Lewis. But yeah... Pick is still Gane and I wouldn't be surprised if he finishes Tuivasa.
Gane's defeat has ruined his unbeaten career in previous fights so I'm not sure Gane is better than Tuivasa, based on the review in the last fight then Tuivasa will be very dominant for next week's fight, I believe Tuivasa's career will get 6 wins in a row after defeating Gane. But I hope Gane can fight again with Francis because he is at the top of the heavyweight championship challenger list.
