They are playing well and certainly have potential to be AAs, but whether they'll get to the point of being recognized as a top 10-15 player in the country is a different matter. Players just don't improve under Holly. Keep in mind Holly has coached the following players, and none of them developed into All-Americans:
Bashaara Graves-former NFOY and top 5 recruit
Diamond Deshields-former #3 recruit and NFOY
Mercedes Russell-former #1 recruit
Ariel Massengale-former #3 recruit
Cierra Burdick-former #4 recruit
Jaime Nared-former #6 recruit
AA honors are heavily reliant on team success. Tennessee is a borderline NCAA tournament team with 3 really good players on the roster in Westbrook, Davis and Zaay Green. Will Tennessee get over the hump once Horston comes on board and the young players are upperclassmen? On paper they're a top 5 team in the country next year, but Holly's history says they'll continue under perform if she is still coaching. This is 4 straight years of abysmal results despite coaching 9-10 top 10 recruits over those 4 years. If Tennessee isn't a top 10-15 team, none of their studs will make an AP team.
Graves - didn't help herself. I don't recall her spending countless hours improving her shooting distance. She had the post player skills, but was undersized. Needed to do more to extend her own range.
Deshields - came in with a horrible leg injury, but I won't disclose the details to that injury. Even today, she is not the player that she could have been. Her own father has acknowledged how the injury impacted her.
Mercedes - probably would not have been #1 had anyone known she was entering college with 2 horrible feet and both required surgery. Her movement isn't that great. It's not a matter of skill, but something no coach can fix.
Ariel - lost a year and half due to concussions. I recall her being voted NCAA Player of the Month prior to the head injury and she never was the same after. Her minutes had to be watched her senior year, even.
Cierra Burdick - displayed the skills her senior season, but face it, she had slow foot speed. Coaching can only make a player so quick.
Nared - Honorable mention AA and stuck to the WNBA roster, so not bad.
Today, all the 3 you have mentioned are gym rats that are highly passionate about the game and that goes along way in development.
