I agree with the first part, but not so much with the second. DC although somewhat green in his standup (although he looked fine for a HW) clocked Bigfoot with some hard hits that would have knocked anyone out.
I can see what you are saying as far as the much bigger Overeem with a rep behind him should have hurt him more, but I don't think he landed as solid a shot. Fedor caught bigfoot with some bombs himself and bigfoot didn't flinch. I just think DC hits really hard.
First part was on point though.
I'm a big DC believer and yes he hits hard. But it is sad when undersized wrestlers beat him down. But the k-1 champ and one of the bigger guys in the division can't do much in a standing fight. Overeem was touted as automatically the best striker at HW because he got lucky and won a kickboxing tourney with puffy gloves. He is no where near the best striker, couple that with his iffy chin and lack of resilience and you have 1 overrated piece of crap.
He was winning that fight. But Cain, DC, Werdum, Roy, Hunt, JDS would/have all handle Bigfoot standing as well. His paper skills don't match what I see in the cage. He is slow and chinny.
