It is a well-known fact and established on saddo that Marquez avoided Naz by not really trying to face the dangerous and peak Naz.

Floyd was no body at the time and was at the higher weight which Naz did not want to move up to.

By the time Naz had fought MAB he was past his best, burnt out like a bright star, and fell out of love with boxing.

Naz was the best at featherweight and unified the majority of the major belts but was steadily declining and getting knocked down.
I think they would have been good matches against Marquez, Morales and Pacquiao.

It would have been very interesting how Lomachenko would have handled that style from Naz. Think he could have knocked them all out.
