The best example of the evolution of a bber is Nasser
Sherief has the proof in pics
Nasser 1990/91 had the contemporary physique of the day, he then evolved in the Yates era, and further still in the Ronnie era.
In his early days, he was a big guy, almost at Albrecht size, maybe couldve brought up few things, but looked fairly complete
Later he evolved with more mass, huge legs, big delts and arms, much bigger
Later still, he developed the kind of delts and arms(along with corresponding mass elsewhere) that we are now accustomed to, but seemed impossible earlier in his career, I mean, he looked like he was done, complete, a big guy... Along with a huge lower body that's now common place, and he already had big legs initially, but now they became monstrous
If you think about it, Nasser is quite amazing in the way he evolved.
The same could've happened with Haney. If anyone had a structure for size, Haney did
