Personal Bio/PreCareer SummaryThiero was born in Utah but attended Quaker Valley High School in Leetsdale, Pennsylvania, where he played basketball, soccer, and lacrosse. As a sophomore in basketball, he led the team in scoring, which he continued to do through his senior year when Quaker Valley lost in the Pennsylvania Interscholastic Athletic Association championship game. For his efforts in the 2021-22 season, Thiero was named Western Pennsylvania Interscholastic Athletic League Player of the Year, TribLive HSSN Boys Basketball Player of the Year, and Pennsylvania Class 4A Player of the Year. As a four-star recruit, Thiero then committed to collegiate basketball for Kentucky under John Calipari, who had coached his father, Almamy, in college. Thiero's mother, Mariam, was also a successful athlete, as she was selected 33rd overall by the Washington Mystics in the 2006 WNBA Draft. After relatively quiet freshman and sophomore years, Thiero followed coach Calipari to Arkansas and enjoyed a breakout 2024-25 campaign for the Razorbacks as a junior. Thiero averaged 15.1 points, 5.8 rebounds, 1.9 assists, and 1.6 steals in 27.5 minutes across 27 regular-season appearances while shooting 54.5 percent from the field. Standing at 6-foot-8 with a 7-foot wingspan, Thiero possesses ideal size, length and athleticism for a forward in the modern NBA. He is an aggressive offensive rebounder and has the ability to consistently finish above the rim. Thiero is also a menace on the defensive end, as he proficiently uses his length to create turnovers and erase shots at the rim. Thiero's ceiling will ultimately be decided by how his three-point shot develops, but his elite athleticism and impressive length give him a solid floor as an impactful defender who can crash the glass and finish at the rim. Thiero's game is reminiscent of Jalen Johnson and Noah Clowney coming out of college as lengthy defenders who can be used in small-ball lineups and get to the rim by cutting off-ball or running in transition.
