The middleweight division is actually pretty hot at the moment. GGG and Sergio are the top 2 (provided Sergio has somthing left) barring them tho its wide open imo with Quillin, Jacobs, Macklin, Lee, Murray, Stevens, Korobov, Fletcher, Geale, Ndam, Sturm, Rubio, Lemieux, Saunders and Murata all match up against each other nicely. You also have to throw Johnson into the mix too after his good performance against Stevens.
