That's true, he is optimistic and I think that's is one of the keys to winning this fight. He has nothing to lose but something to gain if ever he defeat Pereira and strips the title from him and back to the waist of Adesanya.
This is a big fight for most Adesanya fans, like me. Because we will never know what his next move will be if ever he is defeated. I think I am not ready to see that just yet.
However in most cases, when popularity dwindles, the company might change their mind, especially when winners are becoming losers or less famous. And often at times, it might be that they just one to try another famous person which is understandable.
In other words, both parties are doing it for the money.
If the business is not making anything out of advertising popular fighters like Adesanya then probably they will let him go. It's not different from how Nike does things. I mean, look at how they just throw away Kyrie Irving after becoming the villain of a religious group. Now he is rebelling and putting tape on every Nike shoe that he wears.
This is also the reason why they are milking them as much as they could while their shine is brighter.
