Most complete fighter who gets all the ticks?

I'll go with Floyd Mayweather Jr. Can't really remember him having a flaw or being exposed yet.

Probably the only one is that he sometimes lay's on the ropes a bit too much.

Hhhmmmm could be but I see it more as his strategy. You have guys just throwing punches and getting tired while he just slips away from them and walks out of the ropes without a drop of sweat. Always comes out clean from his fights.

It didn't work against Castillo though thats why in the rematch he stayed off the ropes at all times, just circling the ring.
