His TDD has improved a lot but DHK will put him on the mat at some point and when he does it will be tough for Kampmann. He's not subbing DHK, who has great sub defense. On the feet Kampmann is clearly the better striker, but he is not the greatest defensively, and Kim will land a few big shots toopen Kampmann for the throws or singles.
Pierce Vs DHK would be a great fight, it'd be a back and fourth grappling match, Pierce would win most of the dirty boxing, and has better cardio. But Kim is deadly in the clinch and I can see him throwing Pierce, where he will then control the fight. Pierce is tough though, the toughest out of the others I listed.
Ellenberger is dangerous because of his power and amazing TDD. But in a clinch if DHK uses his judo he could win the fight.
Kos would go like Pierce for the most part. But I can see Kos using his TDs more.
