All of the people who only watch the UFC are going to be scratching their heads at this but, Manel Kape is one of the best fighters in the world at 135 lbs (or Rizin's Bantamweight which is 134.5).
I know he's fought at closer to 125, I feel he looks better at the 134 mark but, he is a really good fighter nonetheless. The UFC did great by signing him, he has a really fan friendly style as well so he should be a nice and welcomed addition to the division.
I know it would fuck up Rizin a bunch, but I'd love to see Kai Asakura in the UFC as well, not to mention Gooch, who I think is on equal footing with DJ and Henry (or as close to those 2 as you'll get)
