ODP has never tried to be an inclusive entity, but rather an exclusive one. That's been my biggest rant with ODP through the years.
There are several good points raised in this discussion however. But, I also feel that too much stock is being put in "professional" training sessions. My experience is that most 'good coaches' are running quality training sessions, sometimes in more quantity than the so-called experts that simply roll the ball out there and let a hand-picked group of talent knock it around. Yes, the argument can be made that the game is the best teacher, but this is essentially a scrimmage and little "training" is actually being done.
