It's when the praise is so focused on the potential for what the skater might achieve in the future, but hasn't achieved yet, that hype can backfire. There's no way that every skater who gets touted as a potential world champion or Olympic medalist will live up to those predictions. It that level of achievement is considered the measure of success, then most skaters will fall short and be disappointments.
It's probably counterproductive to get readers or viewers all excited about the next big thing when chances are someone else will be playing that role next year.
When it comes to US ladies, I'd much rather see a focus on the depth of the field. Sure, profile individuals, but put them in the context of each other. Get the public excited to tune in to Nationals and see lots of great skaters, lots of great skating, see who will come out ahead this time.
Which might take some of the pressure off any individual girl to live up to expectations of being "the one."
