in so many kids. Baseball/softball, soccer, and basketball. Before they even develop to the level where they are actually growing into their athletic ability, they are burned out. Football is also bad, but not as bad as those three. At least in that sport you aren't playing tackle until a little later. Volleyball has grown as a second sport...the sport you pick after you burned out on your first sport. Travel volleyball is really bad at age 12 and doesn't start looking like real volleyball until 13's or 14's depending on the talent level and coach.
