Who is the best HOF Middleweight you would favor prime GGG to beat?

The guy I believe would lost to GGG in their primes is Bernard Hopkins.

I know they may be a controversial one because Bhop looked nearly flawless at middleweight. It wasn't until he got older and decided to moved up to LHW thats where we've seen Bhop in trouble. Bhop vs GGG gives me the same vibes as the Oscar vs Bhop fight. Which resulted in Bhop winning by ko. Oscar just wasn't used to that middleweight power.

GGG is stronger, more technical, has the better jab than Oscar de la Hoya. Not Entirely sure that Bhop had what it takes to overcome all the obstacles that GGG presents.

With that being said, LETS GET GGG A FIGHT!!!!
