All P4 will be doing it starting this year. Which, honestly, all that matters. Doesn’t really matter what the sunbelt does.
It’s mainly the timing of everything. I’m pretty sure the Big 10 does one report on gamedays. Big 12 has theirs 3 days before the game. ACC does 2 days before. I think SEC does 3 days before as well. Big 10 just does game days. And they all only do it for conference games, which also makes no sense really.
I get they all do it, but uniformity would be nice. There’s no reason not to other than being petty and annoying.
