Keep in mind that a person in BJJ can be a whitebelt in Bjj for more than a couple of years. A white belt that has been training seriously can pose quite a challenge for those unaccustomed to grappling. In addition, a Bjj white belt is a far cry from an untrained person on the street, perhaps I could have specified "three stripe white belt" but I don't think all schools use the same system.
Yep. Being a BJJ brown belt I'm aware of this. I'm also aware that most BJJers are way better at the ground game than at takedowns. Most 3-stripe white belts are no better than mediocre at takedowns unless they have prior wrestling background.
Can you repost the video of iizzo training alive? I must have overlooked it.
Here you go. The guys do eventually get the takedown almost every time, although he would probably have a chance to land some strikes first. Still, the guys he's working with are significantly better with their takedown skills than most BJJ white or blue belts. I give Izzo credit for getting in there and testing his theories and I'd say he demonstrates good enough takedown defense for most street self-defense purposes. It's not good enough for a high-level MMA or grappling match, but it's better than I see from a lot of WC guys.
