Miss St is about to be 3-2. They beat Charleston Southern, La Tech and LSU. Because LSU started the year ranked high, beating LSU jumped them into the top 25. The 2 losses are by a combined 60 (Auburn loss still winding up).
LSU is losing to Troy and should not be considered a top 25 team. However, the SEC circle jerk ranked them high, so a mediocre MSU team gets a 25 win and jumped into the top 25, so UGA and Auburn get blowout wins over a "top 25" MSU team.
