The whole point of being a mover, is that people will struggle with the style! You might not win, but you will definitely throw them a curve ball!
Great point but...consider his entire body of work. I would point to his title match against fellow HoF Buchanan. Duran was only 21 at the time and he walked him down and walked on him.
I only brought up the no mas incident because the thread title is literally "fighters who did NOT struggle with movers". I'm aware he has a very long and illustrious career where he does well against all kinds of styles.
A bit left field maybe ? Carmen Basilio : shakers and movers like Saxton, Gavilan, ans SRR were all at some stage on the receiving end of Carmens body punches, were they not, also he did what SRR couldn't do, put The Keeed on the canvas.
For this to be true it would mean no boxer in history ever went undefeated against movers, and that isn't true.
