INDIANAPOLIS (AP) — Houston’s Kelvin Sampson has gotten a lift from transfers in guiding the Cougars back to the NCAA Tournament’s Sweet 16. The second-seeded Cougars have multiple transfer starters, including Associated Press third-team All-American Quentin Grimes from Kansas. That group has helped the Cougars extend the best sustained run since the “Phi Slama Jama” days of the 1980s. Sampson says teams that don’t take on transfers in today’s game are behind. Transfers are also playing key roles for several top teams. That list includes No. 1 overall tournament seed Gonzaga, Baylor, Michigan and Arkansas.
