young players will have to wait for an indefinite period for their turn.......that is just the way it is.......no more 17 or 18 yr olds will be allowed to win a slam.......nadal will remain the last teenager to win a slam for at least a couple of decades to come.......
ITF wanted to create superstars and run the business with them standing in the forefront, they got that at the cost of losing variety and diversity.......today we have four superstars and the rest playing catch up at almost every event.......
the sport has to change the way it functions for a talented teenager to win a slam again, or for a nobody to take out a top gun in the first round of wimbledon.......for sure ITF are not willing to work in that direction.......and that's not going to happen overnight anyway.......
it will take 10 full years to change back to the days of variety and surprises - changing back the surfaces, corresponding coaching changes, grooming rising youngsters and other related stuff.......
