Remember how popular it was in 2010?
UFC 300 had zero HW fights. Zero. The average UFC card MIGHT have a single HW fight.
This is just some of what 2010 had to offer:
Fedor vs Werdum Strikeforce
Brock vs Carwin UFC
Mir vs Crocop UFC
Cain vs Big Nog UFC
JDS vs Gonzaga UFC
Arlovski vs Bigfoot Strikeforce
Struve vs Nelson UFC
Hunt vs McCorkle UFC
Overeem vs Duffee DREAM Dynamite
Kimbo vs Mitrione UFC
Lashley vs Sims Strikeforce
Walker vs Nagy Strikeforce
DC vs Riley Strikeforce
Rizzo vs Shamrock Impact FC
Pudzianowski vs Sylvia KSW
Sapp vs Weinpolter K1 Croatia
Oleynik vs Grove Bellator
Konrad vs Grabowski Bellator
Minakov vs Sherbatov M1
Coleman vs Couture UFC
Ishii vs Le Banner DREAM
Beltran vs Rolles Gracie UFC
Whether it was a legends fight or a title fight or a freakshow fight, HW was so fun in that era compared to today in the UFC and elsewhere.
Feels like an afterthought now compared to 2010.
