John Blackwell, a former guard for the Wisconsin Badgers, is one of the most coveted players in the NCAA transfer portal. On3's Joe Tipton has predicted a 60% chance that Blackwell will commit to the Duke Blue Devils after taking an official visit to the university. Blackwell, who stands 6-foot-4, averaged 19.1 points per game during the 2025-2026 season, showcasing his scoring ability with a shooting efficiency of 43% from the field and 38.9% from beyond the arc. In addition to his scoring prowess, he also contributed over five rebounds and 2.3 assists per game. Duke, under coach Jon Scheyer, has consistently performed well in recent seasons, achieving at least an Elite Eight appearance in the last three tournaments. The addition of Blackwell could be pivotal for Duke's aspirations of winning a national championship.
