Whatever else can/should be said about Mr. Pellegrini and his system, one has to admitt that he is a Master at marketing. I have heard the stories on how he got his rank and such. Personally, I don't care. What I do care about is if, repeat "IF" the techniques he teaches are valid for everybody to use. I will use page 90 (BB March) for an example. Frame 1&2) He slips to the outside of an incoming right hand punch and uses his right hand to deflect/grab. OK so far. Frame 3) His roundhouse kick reaches all the way across the attacker's body to the lead leg and is attempting a nerve strike. Frame 4) His left hand is getting ready to do something (opened and coming down?) with his focus on the elbow, but in Frame 5 he has made a transition - now in front of the attacker and the left hand that was open in Frame 4, has now switched places with the right hand and his right hand is now on the attacker's shoulder. A note here; the attacker's punching arm has not changed position since the transition, which tells me that the wrist lock that's seen in Frame 6, which has taken the attacker to the floor, was done with the weak hand from an ??? position. In Frame 6) we see that again he has switched hands and now the right hand has the wrist lock and the left is up on the forearm. In Frame 7) now the left hand joins the right in the wrist lock.
I will use Mr. P's words here from the article, describing what he is doing.
"As he closes the gap and initiates the right-hand strike, step forward and to the outside with your left leg. Simultaneously use your right hand to parry his punch, then grab his wrist. The path is now open to disable him with a roundhouse kick to his right leg. Next, use your left hand to seize the elbow of the arm you just grabbed. Lift the limb, then circle it downward while you pivot counter-clockwise. That will cause him to fall on his left side."
Now either this was written wrong or I'm a total moron or the laws of Physics have been altered. What is seen and what is said don't compute. One would have to view the article/pictures to evaluate for themselves. Even with giving the bennefit of the doubt that the technique in question is plausable, there are still elements of the technique that beg, in my opinion, for change. Case in point: Why roundhouse to a front nerve in the leading leg? Instead, roundhouse to the groin or stomach. Even better, a sidekick to the nearest leg, in this case the attacker's right leg, which would force the attacker's body to go into the direction that Mr. P wants him to go anyway. This way the attacker is falling and you don't have to stand in front of him during the transition phase, which if the kick was not successful in it's intent, your giving your back to your attacker while he is still a threat. It just looks like this technique is being forced, there dosen't seem to be a natural flow.
I'm always open for learning something new, so if I am missing something here, please feel free to assist in my education.
However, if it is possible to put loyalties to one side and just examine the biomechnics of what is done independent of who is doing it, there is the promise of a very informative string here. Now, I would need a bit more info from Mike about the technique and what was done, as compared with how he would execute the technique, and this can get a bit laborious, if not tedious. All the same, I think the promise is there. FWIW.
