I love Shale but their is a reason why he took a cocktail of drugs and cut 20-25lbs to fight at middleweight instead of Light Heavyweight. He was an elite middleweight but got absolutely buried by anyone who had size and strength advantage and could put and keep him on his back, see his fights with Rashad and Tito for reference. Using DC is a poor example because he was initially an undefeated heavy who only moved down because of Cain, and he fights better heavier, more knockout power and can take shots better. So no, this is ridiculous and weight classes matter for a reason. Even past their prime heavies who weren't very good to begin with bodybag the lower weight class elites, Chris Tuchscherer could roll off his couch and destroy Conor McGregor today without a camp and Christian Morecraft would body Khabib
