He has no choice though but to get to Donaire. Same with Donaire, he was tearing the division and fighting young boxers and getting the belt. But in the end they have crossed path and as that Donaire was at a disadvantage because he lost his belt again. Nevertheless, he will have another chance to win it because he will be fighting for the belt, while Inoue will do it but in different weight class as he will challenge Fulton for his 2 belt.
What we witnessed in the fight was a real competition, the fight between the best versus the best. Hopefully, we will also see the same in a different division, where champions don't evade fights against opponents they think could defeat them just to maintain their undefeated record.
Donaire was a great example of a true champion, as he was well aware that Inoue could beat him again, and yet he still risked a unification match to test himself against Inoue once more.
