I don't know if there is a link. I happened to see that episode while at a friends house. As I remember they had Jason at a training faclity in Israel. They did a kind of baseline test by having him and his buddy defend against an attacker with a blade. His first attemtp to defend was less than successful. After he went through the program at the facility he was able to improve his performance. In the end he went against multiple guys, some armed and did very well. I believe that he was able to pick up the Krav techniques so quickly in part because of his atheletic and mma experience.
