This is Mark Tripp. I am going to suggest that until people get to know you, you might want to be a bit less defensive. On the internet it doesn't help much. People are going to disagree, taking it personally is never a good idea.
No one is saying anything except it is an unusual way to discuss/teach the technique. O goshi for beginners is almost always a problem. If your way works, great. I have found it easier, and more effective in the long run, to teach Ogoshi in the manner found on the first set of Gracie Jujitsu tapes (close the gap, clinch, throw). X in the box step is an odd motion for beginners. However, my way is just that, my way, or more correctly the Gracie way.
I know all the people you are speaking of, and they know me. Lets add Steve Scott and John Saylor into the mix as well. That said, my knowing them doesn't make my classes or abilities any more or less than what they are. It does help that they all speak well of me, and know who I am, because Mike Swain, Steve Scott, and John Saylor have all seen me teach classes.
This "feeling out" process is a major part of Bullshido. You are not being asked to do anything the rest of us didn't have to do. As such, I really want to hear more about you winning the Pan Am, and those Marine Championships.
Thanks, and again, welcome.
