As a fight fan I was frustrated by the lack of care Sapp had for many of his fights, then the way he often quit a fight early in the first round even. But I've come to understand something: Sapp does not consider himself as a fighter, he considers himself as a businessman. And for that reason I think what he's doing is just fine. There's supply and demand, and if people want to see Sapp, and pay for Sapp - which happens around the world, in particular in Japan where Sapp has more of an entertainment role these days (see various TV shows he appears in), then that's fine.
Sapp tried to make it in the NFL, but failed. He went into depression, and one day he got a chance to partake in a toughman show. He was discovered, and the rest really is history. He managed to maul one of the greatest kickboxers of all time, twice, which is quite the feat. He destroyed Japanese fighters, and he nearly defeated Big Nog, who at the time was the best. He made a huge splash, and he earned a lot of cash. But I assume around the time of having fought CroCop, and Fujita, he reconsidered what he was doing, because clearly he did not enjoy it. So where you have someone that practices a martial art or MMA their entire life, this was not what Sapp had done, he was basically given an opportunity to make money through MMA and K-1. He did make money, but it wasn't his passion.
Due to his size and personality, he was able to keep making money, and he could've spent it all on drugs, hoes, and nonsense, like too many other people are, but he has invested a lot of it, and he keeps getting appearances in commercials and TV shows in Japan, obviously something that helps paying the bills.
Since he is open about this, and isn't trying to pretend to be a fighter, and gives us a lot of excuses as to why he's losing or why he isn't performing, but instead just says it like it is, I think it's fine.
Of course it's hard to be Mr. Random Average Guy trying to do the same and make equally sound investments when you're struggling to make money in the first place, but even so, Sapp has a point. Where is your end game? If there really is no chance for you to have an end game in MMA in the first place, might it not be more appropriate to look at other options. Is potential glory as a future champion the only thing you are capable of succeeding at, and is this the only thing you care about? Is there nothing else?
There can never be a thousand champions at the same time, all equally famous, popular, and rich. There's only a handful. We praise these people for being legends, and it's true some of them have had fantastic fights and shown us a lot of heart, but look at Gary Goodridge how he struggles these days. What if Big Nog ends up like this as well? Or other fighters? All because of the chance at glory or some such idea.
Like Sapp said, people are trying to run towards the finish line, but they don't even know where it is, so instead there's people running off a cliff. They end up with poor health, incapable of enjoying life, with their family and friends. That cannot be good at all.
Sapp is in a unique position, but even so, I think some of the things he says is sound and it's something people should consider.
