Adrian Martinez, Dillon Gabriel, Quinn Ewers and JT Daniels understandably topped the preseason lists of players transferring to Big 12 schools.

When No. 17 TCU (4-0, 1-0 Big 12) visits No. 19 Kansas (5-0, 2-0) on Saturday, a combined eight starters and several key backups will be first-year players for the Horned Frogs and Jayhawks after having played at other schools.
