I was there and I remember, but if we're being honest Bob Sapp always sucked.
Massive lack of coordination and basic motor skills, stiff as a board, terrible cardio, and no heart. He got popular real quick in Japan because of his size, showmanship, and ability to crush overmatched and vastly oversized Japanese cans, then followed it up with an entertaining loss to Big Nog (a lot of fighters back in the day were able to look good against him early, before succumbing), then managed to stop Hoost twice... AHHHHHHH!!!! Those two fights with Hoost are probably the most frustrating kickboxing fights I've ever seen in terms of the better man managing to lose but for those who haven't seen them here they are:
One loss via cut after a bunch of illegal shots when he was down and after the bell and an early stoppage in the other. And look how bad Sapp looks doing it! Still, he holds two dubs over one of the greatest kickboxers of all-time while simultaneously being terrible at fighting. You're also right, when he faced a legit kickboxer in his prime with fire in his belly and hate in his heart we finally got to see what Sapp was made of.
And it never really got better from there.
Sorry, but the Bob Sapp period still irks me to this day.
