This is something that Geno has mentioned over the years - as far as how the game has changed for younger players. They spend far more time working on flashy things and much less time working on fundamentals. Kids also don't want to work as hard as those 15-20 years ago. So it becomes more difficult for the UCONN coaches to evaluate players and see which ones would fit in at UCONN.
I think Gabby Williams is the perfect example, though for a different reason. She was injured and basically unable to play for 2 years. That severely restricted her ability to practice and improve, and brought her to UCONN with limitations to her "guard" game. BUT... the kid worked her butt off, embraced a new role, and is now working hard over the summer to improve her guard skills. I believe it's the attitude and work ethic that Geno and co. saw in her that has made, and will make, her a terrifically successful UCONN player.
