Ruhl..!..he is so full of synthol it is hard to determine what type of genetics he really has. Are we talking genetics or downright ugly physiques ?
Before Wheeler played the mass game, his body was near perfect in most eyes. I still have to give him my vote for all time best genetics. Also that pole smoker Bob Paris, he had great shape.
I have to agree with HIT on Jackson as well, more size and he would be great.
Worst....let me think...Ruhl, Kovacas, Dillet, Kenny Jones ( but he has no body anyway to compare), McCrary for sure.
