Divisions made perfect sense when the SEC invented them, I think back in 1992.
If your conference has grown so large that a round-robin isn't feasible, then split it in half, with each half playing a round-robin amongst itself, and then the two group winners face off in a championship.
That was the model everyone went to. And mostly still do.
I remain unconvinced that there are valid benefits to the single division/two best model.
This year, it would've "allowed" the Big Ten to select Ohio St and Indiana to have a rematch in Indy.
For me, that isn't a valid way to do it. But, that is a subjective discussion.
Ultimately, this is likely to mean fewer championship appearances for western Big Ten teams, and more games between the elite Ohio St, Michigan, and Penn St.
So I vote no.
