The trajectory of Sammie is similar to that of LJ Rose a decade earlier. Like Sammie, he matured early, and like her was considered the best in his class by his frosh and soph years in high school, leading many to believe that he was a sure thing for college success, with possible professional aspirations to be realized. Sammie actually sustained her success in high school more than Rose did, but like him, found that the transition to the next level was shadowed by a lack of quickness and speed, and a vulnerability to the defense and mobility of players of equal or greater size.
I watched a televised game between Sammie's high school team when she was a senior, and a visiting team from Los Angeles, and I was surprised at how passive she was when guarded by a tall, athletic opponent. She managed a few points late in the game, but one would never guess that she was considered to be an elite talent by her playing style, despite an obvious set of skills which would enable her to succeed in contests typical of most high school.
At the time of her decommitment I noted on this board that I doubted that she would ever merit the high ranking that she had enjoyed earlier in her high school career, the same impression I had of LJ Rose as I watched him for the first time in a Baylor practice. These kinds of players, without regard to their assets off the floor, are traps for college coaches who have recruited them because when they do not perform at the level predicted by their high school careers, the parents and fans of these players assume that it was because of the coaches' decisions and teaching techniques, and more than a few of them wind up transferring, sometimes more than once. We see this in every sport, especially in situations where age is a contributing factor in dominant performances.
