danowak: I was thinking the same thing about "it's gone about as far as it can go."
I wonder if people haven't thought that about many things in the past. At one time, a car that went 45 mph was considered "breakneck speed". Who would have thought 100 years ago that medical technology would allow all the surgeries & procedures that are done routinely today, etc, etc.
I'd say that the sport will continue to evolve, and it's hard to say where it will stop - if it does.
