For Me Leandro is actually proving in reality, that his technique transcends different weight clases... Just like Kyle Dake did... which also has bearing in P4P discussions
Rafa's weight class is not competitive after Cobrinha who is there?.. They are miles above everyone else... Grippo, Mario Reis, Moizinho, Samir Chantre... Marcio Andre did flip things up last year but he has been competing a Lightweight this year
Compare that to Lightweight Lucas Lepri, JT Torres, Edwin Najmi, Roberto Satoshi, Michael Langhi, Gabriel Rollo, Francisco Iturralde, Michael Liera
I actually think Rafa could move up and do well at lightweight... Regardless his division is not as competitive as Lightweight
