How does one identify a star, particularly if that athlete isn’t at the top of the recruiting rankings?
For Craig Skinner and Kentucky volleyball — postseason regulars for each of his 21 years in Lexington — there is no shortage of interested talent. The most important marker, then, to become a Wildcat, is whether or not someone fits the identity of the program.
“I think it’s really important in recruiting, sometimes you have to say no,” Skinner said. “And what I mean by that is, there’s a lot of really talented players that other people think are really talented. And so if they’re saying ‘Yes, we gotta go after this kid,’ it’s OK to differ in your opinion.”
Kassie O’Brien wasn’t necessarily the most-touted player — let alone setter — in the high school class of 2025; Prep Dig classified O’Brien as the sixth-best setter in the class.
But every time Skinner and his staff went to watch O’Brien play, “it was all-in, all the time,” Skinner said, whether for the nationally renowned Houston Skyline volleyball club or Cinco Ranch High School in Katy, Texas.
“There was never anything about her that said, ‘I want to be really good. It’s about me, and I’m going to get all these accolades,’” Skinner said. “And so, when she was on the court, she was fighting like hell for her team, whichever team that was, to win this point, not the match, the point at hand. And so, all setters, all players at that level, have things they need to get better at and improve on. And she was no different in that area, but psychologically, she was who we are as a team in our program.”
That approach has helped O’Brien on Kentucky’s path to the NCAA Final Four, where it will play Wisconsin on Thursday in a national semifinal match.
O’Brien, the younger sister of former Texas Tech middle blocker/outside hitter Maddie O’Brien and current Florida International outside hitter Courtney O’Brien, said she’s always been a team-first athlete.
The self-proclaimed “super-competitive” setter grew up with her sisters inspiring her to “want to be better.”
“From when I started to when I just continued to grow, I always just wanted to be that fighting competitor that goes out there and gives it their all every single time,” O’Brien said. “And I wanted to — and I still do — just be someone that’s positive on the court, that my teammates can look to me, you know? So I think that’s just been something that I’ve carried out throughout my career.”
While with Cinco Ranch, O’Brien eclipsed 4,000 career assists and helped push the Cougars to their second-ever Texas 6A state tournament appearance; O’Brien and her teammates reached the 6A Regional Final before falling to state runner-up Fulshear.
The state of Texas is a hotbed of elite volleyball talent, which meant that O’Brien — who played for one of the top club programs in the Lone Star State — was consistently battling alongside and against some of the strongest prospects in the country.
O’Brien is one of three native Texans on this season’s Kentucky roster and one of 13 players in program history listed as hailing from Texas.
“Props to them for being able to help me grow each and every day,” O’Brien said. “And then also being able to play so many other competitive teams within our state, not even having to travel outside of Texas all that much. I definitely think it’s a huge advantage, growing up around and being able to play against those teams and those players because so many of the girls that we play against now are from Texas. It’s super cool seeing how big volleyball is in that state.”
At Kentucky, O’Brien saw an opportunity to continue her development in another high-level environment where the culture felt like a fit.
“The coaching staff and the culture,” O’Brien said. “I remember watching them play in the national championship in 2020, and just the legacy of setters that they have had here kind of made me eager and want to be a part of that, too. I just knew that this was a special place that I really wanted to be.”
Kentucky has featured setters like Jane Belanger (1990-93), Sarah Rumely (2006-09), Madison Lilley (2017-20) and Emma Grome (2021-24), the latter two of whom created a strong sense of stability for the Wildcats with consistent, championship-level play at the position for nearly a decade.
Desperately wanting to get a head start on adjusting to the collegiate level, O’Brien enrolled early in January of this year and understood that she would be competing for the starting setting job with redshirt sophomore Ava Sarafa.
That battle was, she admitted, a bit intimidating.
“It was definitely nerve-racking at some points,” O’Brien said. “Because those setters before me just had such…legacy is what I’ve said. So, I mean, it kind of puts pressure on you when you come in and you don’t really know. But I just think the coaching staff and my teammates have just always pushed me and kind of believed in me ever since I stepped foot in here, and I think that goes a long way.”
Skinner often refers to the setter as “the quarterback,” of a volleyball team’s offense. Though O’Brien entered the season lacking the experience and accolades of Lilley and Grome, her teammates view her as an indispensable piece of the Wildcats’ high-powered attack.
UK junior outside hitter Brooklyn DeLeye called O’Brien “one of the hardest workers out there,” and praised the freshman’s adaptability.
“She’s just so easy to work with,” DeLeye said. “If you tell her something that you need, she will immediately make that change. You know she’s working so hard to get you the right ball. I mean, that’s just truly what you need in a setter. I think she’s adapted to the game so well. She got on here and just had swag right away. That’s cool to see from a freshman. We’ve all been in that position. It’s really tough changing from high school to college. I think she’s just done a great job.”
On Wednesday morning, O’Brien was named the AVCA National Freshman of the Year, becoming the first Wildcat to receive the honor. She was also named an AVCA second-team All-American. Those accomplishments join a continuously-growing list of accolades including SEC Freshman of the Year, and All-SEC first team recognition.
“All the awards she’s got have been so deserved,” DeLeye said. “Like, she truly deserves it all.”
Through the Elite Eight, O’Brien has played in 108 of the team’s 111 sets and recorded 1,190 of the team’s 1,546 assists. The setter has also tallied 48 kills, 25 service aces, 231 digs and 84 blocks.
She orchestrated the Wildcats’ offense to a ninth consecutive SEC regular-season title, a 15-0 conference record, an SEC Tournament championship and a top-line seed in the NCAA Tournament.
“It kind of feels surreal and like a dream come true,” O’Brien said. “You have all these big goals that you set for yourself when you come, but you don’t ever know what it’s going to be. And so, getting these awards, it does, it means a lot. I’ve just been putting in so much work, so it feels rewarding. But I just couldn’t do it without my team and this program.”
The lone underclassman All-America honoree surrounded by vets — DeLeye and senior outside hitter Eva Hudson were named first-team All-Americans, while junior libero Molly Tuozzo earned third-team status — O’Brien said the majority of her growth on the court this season has come in the form of vocal leadership, confidence and energy.
“Coming in each game, I’m not so nervous anymore,” O’Brien said. “I kind of know what to expect and know what my job is and know how to do it to my best ability. I think (I’m) just growing in that each and every day, and it’s continued to get better as we progress through the season. That confidence piece has been huge, just knowing my ability and going out there and doing my job.”
The growth through experiencing the season alongside her teammates while navigating the gauntlet of Kentucky’s schedule echoes the lessons learned from her prep career in Texas and at times catches O’Brien off guard.
“It’s hard,” O’Brien said. “Because you’re surrounded by this, you don’t really realize it. But I do take a breath sometimes and like, ‘Wow.’ It’s so special to be a part of this group, and have so many elite players on this team. And the stability of all of us to be able to play together as one is super, super cool. You don’t get that in many places…They help me grow in my game, and we help each other grow in their game.”
Since her early arrival in January, O’Brien has seen the fruits of Kentucky’s labor. It’s that growth, that connection and competition, that gives her hope for a successful weekend with Kentucky two wins away from its second NCAA title.
“I think that’s a huge part of it,” O’Brien said. “Being able to have that chemistry all together and be able to start from Day 1 in January. And here we are in December. So we’ve been together for a whole year, and you don’t really see that often, with your whole team being here in January. I think that’s something that’s super special, and we’ve just been working so hard.
“This team has what it takes to get there, and we’re super excited that we’re here.”
