Well that's a very loaded and interesting question.
Evaluating the young women while in high school is very subjective. Sometimes it's easy to look at a player like Maya or Stewie or Griner or Ogwumike and realize that they are not only the most talented in their class, but they also probably have the most potential. Other times you look at a player like McCaughtry, or Beard, or Dolson, or all the other players that the recruiting evaluators got "wrong" and say "they don't have any idea what they are doing".
I don't know the exact order of importance, and they are many on here who are smarter than I, but there is an incredibly long list to look at, and some of it changes depending on the position they play.
But in general, I'd be looking at a players' size, athleticism, potential, and skills.
Size - to me these aren't skills, but fairly obvious physical observations of the players' physical gifts:
- How tall is the player for the position they play?
- What is their body type?
- Does the player have the ability to gain or lose weight, depending on the need, to maximize her potential
- Does the player know how to use her size to her best advantage?
- Can they be effective in traffic?
- What about if they are double or triple teamed?
Athleticism - also seem like they would be fairly obvious - some kids just "look" athletic
- What is her leaping ability?
- What is her lateral movement?
- What are her reflexes like?
- How quickly can she get up to full speed?
- Can she accomplish skills at full speed or does she lose control?
Potential - probably the most subjective, but what is the players' ceiling?
- How coachable are they?
- How do they react to criticism?
- How do they react to adversity?
- What is their general attitude?
- Are they "team players" or "all about me"?
- Are they good, or bad, leaders?
- Do they encourage teammates or do they criticize?
- If things don't go their way, do they try even harder, or sulk and/or give up?
- Just how good can they realistically be?
Skills - what can they accomplish at this time in their careers?
- Can they use both hands equally effectively?
- Outside shooting? 3-point shooting?
- Mechanics - do the have good form in shooting?
- Do they have good court vision?
- Do they possess high BB IQ?
- What role are they best at?
I'm sure there are many more questions that I'm missing, but it's not just about looking for the most talented kids in the class. I can't tell you which of those 4 is the "best" player because they are all so different. Diana won 2 NPOY awards, but neither time was she close to being the highest scorer, nor was she tops is assists, or any other guard categories. But she had leadership qualities all in one body that no other UCONN player has ever had all together. My point is a player can be great without really putting up "great" numbers day in and day out...
