Nothing in that article talks about the SEC getting rid of divisions. Only points out that the ACC got rid of them after moving to this format.
The SEC likes having divisions because limiting their best team's losses benefits the conference.
(This is just an example)
Let's say in the future Georgia only wins 9 games but still wins the East. Meanwhile Alabama and LSU both go 11-1 in the West, with Alabama losing to.. Ole Miss by 10 and LSU losing badly to Alabama.
Avoiding an Alabama LSU rematch likely guarantees the SEC 2 playoff spots. Alabama would be a heavy favorite in the conference championship game against Georgia, with LSU guaranteed a playoff spot because they avoided the game altogether.
Without divisions there would an Alabama LSU rematch, and if Alabama stomped LSU for a second time, the SEC misses out on a 2nd playoff spot and everything that comes with it.
So let's see if they ever get rid of them. My money is on not a chance in ****.
