No, Dan Henderson is Top 10 all time. Pacquaio is great but not typically in the top 10 all time boxing ranking. Even if you have Hendo ranked lower than that, I think a comparison to Pacquiao is perfectly legit.
Dan Henderson never fought at 170 lbs ever btw.
Semmy, Randleman, and Coleman (in 2004) were top 10 actually. Fujita as well according to MMANews.
This ranking here comes from
@Fioretti actually. I assume it is MMAWeekly since that is his usual go to. Semmy is #10:

5. Pedro Rizzo
6. Mark Coleman
7. Ricco Rodriguez
8. Igor Vovchanchyn
9. Mario Sperry
10.Semmy Schilt
Coleman in 2004 can be found
here.
This is an archived ranking from just before the 2004 PRIDE GP which has Coleman at #8.
If you scroll down slightly from that Coleman ranking, you’ll see an archived ranking from June 2004 which has Randleman ranked at #8.
Not all outlets ranked Fujita, but it appears MMANews did. It looks like this, and link is here.

Goodridge I don’t believe was ranked, and personally I don’t count him as a ranked opponent for Fedor. He really doesn’t deserve to be considered a can or scrub though, I say he’s a good or “decent” win. Not a ranked win though.
