The Big 12 conference is experiencing significant roster turnover through the transfer portal, with DJ Lagway heading to Baylor bringing elite quarterback talent. Arizona added TE Cole Rusk from Illinois, who has 56 career catches and FCS All-America credentials, while Arizona State secured dynamic receivers Omarion Miller and Reed Harris to bolster their passing attack. These newcomers address critical position needs across the conference.

BYU strengthened its linebacker corps by adding Cade Uluave from California, who recorded 235 career tackles including 97 last season. Arizona's Rusk provides immediate help to a thin tight end room that struggled in 2025 with just 36 catches from its top two players. The Sun Devils' receiving duo combined for 84 career catches and 13 touchdowns, addressing a major need after losing their top receiver.

Each program strategically targeted players who could swing next season's championship race. These transfers address specific weaknesses while adding experience and talent to rosters across the new-look Big 12. The influx of proven contributors raises the competitive level throughout the conference.
