Wow, adult triathletes can be such an argumentative lot!  I consider myself a former great swimmer and a very average runner. If I asked a great runner for advice on my technique and paid that person, why on Earth would I then argue the answers? I don't get it! So I'm kind of ornery today because I keep hearing the same stuff, and some of it is downright wacky! And I have to engage in these strange arguments about things that I obviously know a lot more about than the average person (swimming, for example). For the record, I do NOT like Total Immersion, although there is some overlap in that program and in how I teach. There is some overlap in how EVERY coach teaches with the TI program, because we are talking about the same thing: shipbuilding and how to build an efficient craft. There aren't all that many different designs that work. And no, they (TI) did not invent it! None of this stuff is new, but marketing methods are so good now. Shoot, that guy could sell sand to Egyptians and they'd buy it!
