I actually think it has gotten better over the past 10 years:
1) Go to any level JO tourney and the courts are packed with teams/girls that know the game, the biggest change is more athletes are playing the sport which leads to deeper teams than what you saw in the past. Outside of lax it is the sport with the highest % increase in participation among girls.
2) And with more athletes comes a new type of game with an emphasis on speed and quick transition between offense and defense. No more lumbering middles standing there cheating to the outside hitters or smallish setters rotating out when they come to the front line, speed and athleticism are a lot more crucial then it was 10 years ago. UNC has a 6'7" setter slated to start next season, 10 years ago that girl would be stuck in the middle or probably be playing basketball.
3) With regards to coaching I think it has gotten better too, especially now that the 1st big wave of girls that grabbed on to the game when rally scoring was adopted are now turning into coaches especially at the club level; these women can really relate to the girls on the court. In game coaching is more mental than anything else, give me a good psychiatrist as a coach and let the setter run the plays and everything should be OK.
