Dude, I hate Ellenberger but he is fighting Hendricks right now who is at the doorstep of a title fight, so regardless of what happened in the past year, he should be higher than Kampmann at the moment. Kammann lost in 0:46 seconds by a devastating KO and was out before even hitting the ground. I am sorry to say but that shot him down in the rankings.
Getting the fight is not the same as winning the fight. If Ellenberger beats Hendricks then I can understand a top five ranking because he's accomplished something. This would be like having Big Foot in the top five because he was facing Overeem. Now that he's defeated Overeem is Big Foot the number one contender? Would Big Foot now be higher ranked than say Cormier or Mir or Werdum or Barnett?
