Let’s see him fight a live body before comparing him to the 3 legends. Marquez peaked very late so he may very well get better but as of now it’s inconclusive to even speculate if he can compete on those guys level.. Marquez and Morales definitely lost fights that guys on their level shouldn’t have though.
There would be at least 2 loses on his record, and a high probability a 3rd too. I give him a chance against Morales, because EM liked to mix it up.
MAB is just too small for 135. Morales & JMM are naturally bigger and they carried the weight better so they have a better chance to beat Davis at 135. I don't think MAB can beat Davis. Just telling like it is.
Morales would actually murder Davis. And he would do it fighting the exact fight Gervonta would want. Same as he did to Manny. Marquez outboxes him easy & Barrera pushes his 5hit in too
All 3 would be heavily favoured to beat him, especially Marquez and Barrera who are counter punchers. And Morales could mix it up with as he went toe to toe with Pacman.
