"Plus you cant win advanced and expert unless you have skills."
And the majority of TSK competitors are in neither of these divisions. If you break down the total point stat down into average point contribution per competitor, and compare it to that of ATT, Renzo's, and so on, you come to the not-so-shocking conclusion that TSK has that point total due to having a higher regular volume of participants, higher than every other NY area school.
As far as Tiger's karate, remember he was preaching quite a different tune in terms of techniques as early as 6-7 years ago, still his traditionalist oriented program - and talking smack about MMA. Then came more MMA to the area... and getting his elbow popped by Rodrigo Gracie ("oh but I didnt tap, I'm a real warrior!"), and so on. Wow suddenly the exalted karate of Tiger's program suddenly starts including.... Muay Thai? Submission fighting?
Tiger has had more than a decade of shady background, including problems with the attorney general for illegal contracts, telling his students he was trained in BJJ by the Gracies, and so on. And then making a big stink at NAGA and pulling all his students. He and his chain have legitimately earned the right to have people be skeptical.
