The highest ranked team from G5 gets an autobid to NY6. UCF each of the last 2 years and clobbered their opponents. Houston went recently and smacked FSU. Boise has been.
Boise, SMU, Memphis and Cinci are all the front runners for that spot this year.
ALSO - BYU has no such access as they are not G5, nor are they classified as P5. BYU has the worst post season access of literally any program in D1 football.
