Demetrius Andrade vs. Gennady Golovkin.

Not a big GGG fan so could be wrong but he seems like the clean living and even keeled type, they age well and bounce back from adversity (wish I could say I know this from experience, alas not).

GGG has seen Andrade's type before but Andrade has never seen a GGG, so you have to give GGG the edge here unless he bombs in his upcoming mandatory.
