He's a R-FR, so he'd burn a year if he transferred. I guess he could play JC then transfer. WSU lucked into Leach, and he's 100% the reason Cooper chose WSU. Not likely WSU hires a coach as QB-friendly as Leach.
NEXT SEASON:
John Bledsoe R-JR
Cammon Cooper R-SO
Gunner Cruz SO
Aaron Angelos SO
Jayden de Laura FR (2020 class)
Even more unlikely Cooper finds his way to BYU, but I'm inclined to believe the BYU coaches would take him in heartbeat.
NEXT SEASON + Conover:
Zach Wilson JR
Jaren Hall SO
Baylor Romney SO
Rhett Reilly SO
Mason Fakahua FR
Sol-Jay Maiava FR (2020 class)
Jacob Conover Mission (2021 return)
