There is a very clear difference between Alabama and Auburn. Just like there is between Georgia and Georgia Tech. And Ohio State and everyone else. It’s recruiting and money, and how much money they spend on recruiting. You can argue the difference between Alabama and Georgia is coaching, and you’d be correct since Georgia actually outspends everyone in recruiting. But when Alabama is outspending Auburn, a top tier program with a national championship in the last decade, by $2M just in recruiting, it makes it impossible to compete. The difference between Georgia and Tech is even larger. Coaching only truly matters when the talent levels are relatively similar. When there’s a stark difference in talent, coaching becomes almost irrelevant.
