Mostly it’s a “they were ranked last week and they beat this week’s opponent soundly.”
Off how poll trends generally go, they lost their first game to a top 10 team by 3 points, and they lost their second game against a ranked team (now also top 10) by 1 point at the very end of the game.
It’s sort of a voters giving them the benefit that with how well they played against two top 10 teams, maybe it’s more a reflection reflection of the fact that they had to start the season with two top 10 teams and not that they’re actually overrated and terrible.
…The next loss will drop them like a rock though.
