You cannot judge the human body this way it can transform over night in certain cases, for example, Ronnie jumped from 9th to first in one year, so it can be done, and yes the back is mkost definatle as important as the front.
Ronnie was the right guy in the right place at the right time , 1998 was a transitional time Yates retired , Flex was slightly off Ronnie completely dried out and walked away with the Olympia
Wolf's calves aren't going to improve ( naturally ) this long in the game if it didn't happen by now its not going to happen , he could improve on his back he has the width , just needs thickness , detail and density especially in the lowerback but guys like Francios made huge improvements in his back after turning pro
People get excited about Wolf and rightly so however it reminds me of these guys who make all the blanket statements about Dillett & Oliva while having outstanding genetics for muscle shape , length , width and structure it doesn't mean they should win on those merits alone , thats not how contests are judged
Wolf has all the tools to beat Cutler , just like Flex had all the tools to beat Yates but in this sport nothing is set in stone.
