Forget Gane, Jones couldn't take Dominic Reyes down, and he couldn't keep Thiago Santos down, so what makes you think he could either take (or keep) Alex Pereira down?
Worse, in the standup, both Dominic Reyes and Thiago Santos both made Jon Jones look bad, and Alex Pereira could whip both Reyes and Santos on the same night in a kickboxing fight.
Therefore, how in the world do you think Jones has "an easy win" or some kind of "lock" here against Pereira?
Even in his prime, Jones barely be Alexander Gustafsson, who is absolutely nothing as a kickboxer compared to Alex Pereira.
The fact of the matter is, right now, Jon Jones is decrepit these days, while Alex Pereira has never looked better.
