Felix Sturm
Strum lost to the afore mentioned Geale in 2012 and he hasn’t fought outside of Germany since 2006. I don’t see him being on GGG’s radar this year. The only reason for GGG to fight Strum is to capture a title in a higher weight class (Super middleweight). Strum isn’t a huge name in the US and a fight wouldn’t yield much for Golovkin. Sturm may never receive the chance to duck Golovkin for those reasons.
