Are they even trying to find Overeem competition that's on his level? I'm not bashing Duffee or Overeem, but this is just getting ridiculous.
Overeem is the least impressive champion to me in any organization. He has fought for Strikeforce twice since joining the organization and it appears that either he, or his management team, isn't even trying to find top level competition for him. Outside of the NC with Cro-Cop, and I'm not even sold that Cro-Cop was in top form then either, you have to go back to Pride 33 to find a top level opponent that Overeem has faced.
Duffee could always pull off the upset, but on paper this should be another walk in the park. If Russow could put Duffee to sleep with, I think, the only punch he landed in the fight, I shudder to think of what Overeem is going to do to Duffee.
Enough is enough, either vacate the SF HW title and keep fighting for Dynamite and DREAM or step up to the plate and take on some unsafe fights.
EDIT: By unsafe, I mean fights that actually challenge him and aren't what you would call a "safe" fight with barely any chance of losing.
