For the last month, I've been starting all of my bjj sparrings in training, standing up. That is with me and my training partner both standing. I don't know why the bjj communety always starts fights on knees. It can be because of a problem of space, but IMO I think that this is such a waste of judo skills. About 90 percent of bjj guys I know have horrible judo skills because they never practise it. What do u think about this?
