SAN FRANCISCO — With a couple more victories, Hall of Fame coach John Calipari and his Cinderella squad at Arkansas may become the best magic act this side of David Copperfield. The No. 10-seeded Razorbacks (22-13) already have become one of the enduring memories of the 2025 NCAA Tournament.However, Texas Tech — coached by the considerably lesser-known Grant McCasland — doesn’t figure to be an easy vanishing act.McCasland said following his team’s 77-64 second-round win over Drake that a Sweet 16 appearance for the No. 3 Red Raiders (27-8) “has been our vision for this the whole time.”They threw their low-post weight around, outscoring Drake 50-20 inside the paint a game after making 13 3-pointers in 46 attempts in an 82-72 first-round win over North Carolina-Wilmington.They likely will need a little of both to stop another uprising by Calipari’s Razorbacks in Thursday’s West Regional semifinal at Chase Center. Arkansas — the lowest-remaining seed in the tournament field — reached the Sweet 16 for the fourth time in five seasons with a 75-66 smothering of No. 2 St. John’s on Saturday.J.T. Toppin leads the Red Raiders in scoring (18.1 ppg), rebounding (9.3) and blocks (1.4). He also surpassed the 1,000-point milestone for his career during the tournament’s opening weekend.Darrion Williams, who grew up about two hours away in Sacramento, has scored a team-leading 41 points in Texas Tech’s two tournament wins, including 28 against Drake. Elijah Hawkins, meanwhile, recorded his 800th career assist against Drake.The Red Raiders are trying to reach the Elite Eight for the first time since back-to-back appearances in 2018 and 2019, the latter of which was followed by a trip to the national championship game.Back then, Calipari was still at Kentucky and riding the success of developing some of the country’s top freshmen before their departure to the NBA. The Razorbacks are a throwback to his initial arrival on the national scene, when he took an unknown University of Massachusetts team to the Final Four in 1996.
