To be fair to GGG - he wants the Cotto fight. It's Cotto that wants nothing to do with that fight. So while I agree, GGG's resume is much like Arthur Abraham before he moved to 168, it's not entirely GGG's fault, he's been asking both Alvarez and Cotto for a fight.
Horrible resume, which is what makes the damage he's caused to fans all the more troubling. Mr. Triple G has only knocked out 6 Ring rated middleweights, and look at the psychological trauma he's already caused to thousands of innocents. The best that can happen is that the top names don't allow themselves to become the fodder from which Mr. Triple G would expand his terror. If they fall, the damage spreads to millions of fans.
