agree with everythingClayK said:
As one involved in choosing high school all-American teams, and one who has been "wrong" many times, there are certain things I've learned to look for over the year.
But to begin with, there's a key factor that's often ignored: Are the rankings based on performance against same-age competition, or on potential to produce at a higher level?
Dalayah Daniels (and Gabby Green) are both classic examples of players whose weaknesses were disguised by their physical ability against players of their own age (and thus strength and experience). Daniels didn't have to shoot from outside in club or high school ball because she was quicker than players her size and taller than players who were quicker. When she got to college, both of those advantages narrowed considerably.
Which meant that some key skills had to come into play, first and foremost the ability to score from the perimeter. But the way high school and club ball is structured, there is no motivation for any coach to develop new skills for a player. Parents want to have their child on a winning team, and fixing Daniels' broken shot at those lower levels would have resulted in losses. So coaches kept dialing up Daniels going to her strengths, and when those strengths were no longer enough, she had nothing to fall back on.
Another key skill is court vision and ability to pass. Daniels' A/TO last year was 26/41, which is mediocre for a pure post and pretty much unplayable for a wing. Again, club and high school coaches had no incentive to encourage Daniels to pass the ball to an inferior player -- they were there to win (if they didn't, the parents would put the girl on another team), so when she got it, she shot it.
There are similar issues with the "highly rated" bigs. It's relatively easy for a 6-4 girl to get points and rebounds at the club and high school level because they don't face similar size very often. In the Pac-12, it's every night, so unless you're just a better athlete, you have to be able to pass and make midrange jumpers. As the saying goes, you can't coach size, so a tall girl with reasonable athleticism will always be "highly rated," but can she make jumpers and pass out of double teams?
you could also say a similar thing about any position ... for example, Juwan Howard-Dyson was a high scoring guard in HS because he was super athletic and long, and could blow by most HS competition any time he wanted. However that wasn't true against D1 guards, especially when you've got a 6-11 rim protector and a coach that has scouted your strengths/weaknesses
