Do you believe the nba draft class getting worse every year?

My opinion is yes. because this year nba draft 2011 is one of the worst draft classes. I believe none of them will be all stars or superstars. Why is it every year the nba teams want to draft points guards instead of centers.. they pick way too much point guards or shooting guards.. there arent any great nba centers... except dwight howard. so why not draft more nba centers..
