A slow Angulo got to Lara, I'm positive that Golovkin would too, with a bit more speed and power. He would probably stop Lara with a body shot sometime b4 round 7
Lara is too slick and too good of a boxer for GGG. This fight will never happen, even if Lara were at weight. Lara would tag GGG like he has never been hit before and Lara's straight left has lots of power to hurt GGG badly. We all saw that GGG had lots of problems with B level Adama. He got hit far too often and his defence was poor. He actually got hurt a couple times from body shots. Lara is far better than Adama, moves better is more accurate and faster hands.
Rosado turned GGG's face to hamburger also. If Lara boxes and gives him angles he could win rather easily. If GGG can't knock Lara down or out, he loses by a wide margin!!! Why would GGG stay in a division where "nobody wants to fight him"? Supposedly!! I'm sure he would find plenty of comp at 168...
