Great list of fights from everyone.
Carlos Newton vs Sakuraba deserves mention.
I also like Mark Hunt vs Tsuyoshi Kohsaka, real gutsy performance from TK in his last fight, great way to bow out.
It was pretty much blasphemy that Saku/Newton didn't get mentioned on the first page. At least you manged to get in there with it. Good call on Hunt/TK too. That was fun.
Well, my favorite Pride fights are the one's that are actually competitive (Though, Chonan vs Silva was ******* competitive).
Gomi vs Pulver (Best LW stand-up battle EVER....MMA wise).
Nogueira vs Barnett 1.
Silva vs Rampage 2.
Sakuraba vs Newton.
Sergei vs Nog.
There are more.
I can always count on Damone to mention pure quality scraps.
Saku vs White and Braga, which are both underrated as hell.
Newton/Pele (my personal favorite)
Newton/Renzo, which is really under-appreciated as well.
Nog/Herring 1, which set the bar for every great HW battle to follow it.
Ninja/Sperry was nice and gets no love.
I'm getting carried away, so that's it. Though there are so many more, and I only really covered a portion of my grappling favorites which weren't already mentioned.
