That's very ambitious, but knowing his characteristic, it's very possible that he is aiming to do that.
He wanted to move forward. Once he defeats Makabu, it will be sure that more challengers for him, more fights to expect and more exposure
for his name. I really wanted to see him fight after fight. If in case, he really excels from this division, we never know if he will stay or move again
to another division to see if how far he can proceed.
Being the number 1 pound for pound in the ranking, that's not "very" ambitious to call it. I mean moving forward is every fighter's ambition, but once you become the best in different weight division, that's not called very ambitious, that's called maximizing your potential to measure how strong your body can take. Staying in the same weight division knowing that you dominate it will just make a fighter lazy, impassionate, and will probably won't challenge him anymore.
If I am a boxer and will defeat a higher ranking or weight division than me, I won't stop moving forward. I think that's what every fighter wants to happen in their career.
