He is tall enough and has the reach also for that next weight division. So he would not be so much an undersized fighter in the light weight division. He actually would even be taller than Dos Anjos who is one of the shorter fighters in that division.
However that division is stacked with good opponents and so him winning that title would be pretty impressive. He may be struggling to make that lighter division more than what he is letting on and as fighters get older that becomes increasingly harder to do which is why many eventually move up a division or two from that earlier in their careers. The other thing is that he strikes me as the type that wants to challenge himself as well as establish that he is one of the greatest fighters to ever step into the cage.
Winning that title along with holding his current tittle would be pretty impressive and that I think is what is driving him and the fact that he would not be an undersized fighter at all in that higher weight division.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
