Gane moves fast like a flyweight, you don't see anyone like that on his division even Ngannou will be weary doing the kind of bouncing in and out just 1 round. He likes to be in the safer position where he can attack and get out instantly while also prepared to move away whenever there is an attempt of takedowns.
This is also his best way attributes that will make him win against Tuivasa, Tai wants to get closer, he wants to throw elbows and knees but with Gane, Tai will likely not hit.
Tai have a good kick boxing skills, but he lack fight on the ground skills, while Gane is well rounded and he need to force Tai to fight on the ground. Gane should concern about Tai's fake kick where he only raise his leg for mid-low and the swing it higher to hit Gane. If Tai can do this, we might see Tai would win the fight since heavyweight fighters are have higher power than the lower weight.
