This is a good read. First-let's not speculate too much on the super fight. It could be a decline out of respect, fear, injury, etc. If he (possibly) had an injury and was to compete against a high level/well-know Black Belt and lose, it wouldn't be good. I'm not on his side, just playing Devil's Advocate. It would certainly be an interesting match to see him agains Denny, or Bollinger even. The only issue would be the similar styles and plans of attack. I find it interesting that he seems "against" RG or 10th Planet now, when the 10th Planet system was being predominantly used during his "Ryangle" days while associated with Lloyd Irvin. He has used the RG path extensively, so I would say he has at least a better than fundamental understanding of the path. I would imagine that anything he's doing has more to do with self-promotion and marketing. It's an old sales and marketing ploy when working against good competition: my system/product/service is better than so-and-so's. Their product is inferior and my is superior. He doesn't even have to detail why; if someone buys his Kool-Aid, then he's good to go. Robert Drysdale does similar marketing tactics. Much of his game looks and feels like 10th Planet techniques, but he's the "Nth Dimension Jiu Jitsu". It's all marketing. Drysdale doesn't slam 10th Planet that I've seen.
Look at it this way: if those two well respected and high level BJJ players are copping 10th Planet approach and techniques, it's a compliment. Eddie may be considered like the Eddie Van Halen of no gi: now everyone is starting to sound like him and go out and buy a floyd rose, single humbucker, super strat and tapping with their index finger (guitar reference for those who don't know). It's like the early 80's in rock, only it's jiu jitsu. This kid with the cool name has come up with a new twist on something and everyone wants to be him.
