One of the most underutilized positions or techniques in BJJ are offensive turnovers. Why? Well sport-wise we have grown accustomed to hunting for the collar or the hooks. Some would even venture to say that these techniques are almost foreign to BJJ players. But take a close look at BJJ's other family members - Wrestling, Judo, Sambo and Jiu Jitsu all utilize turnovers to establish both control and pins. We may not have the latter, but the much neglected turnover allows us to reverse a neutral position, win points, and sets up attacks from side control or mount. So open up that little mind of yours and start learning some varied attacks from freestyle wrestling.
