The whole purpose of reserves is to provide relief for they key players. If fans had their way, and it were physically possible, Lebron, Kobe, Carmelo, Paul, Rose, etc.,. would be playing 48 minutes per night.
It is the team and the coaches responsibility to keep their players rested and healthy over the course of an 82 game season + playoffs. If that means sending home the guys that put in 30+ minutes per night a few days early over the course of a grueling road trip, then so be it. The best interest of the NBA should be that each team be as compe ive as possible and do what they can to put out a team that will compete for a championship at the end of the season. Not a team that will make Stern money on a November game at the end of a ridiculous road stretch.
