I don't think you get to say "K St. Ranked #20 then, now #11" Then say "Wisconsin ranked #14 at the time" (you did this a couple times, just one example) it makes your argument inconsistent. JMO.
I absolutely think that the SEC is the best conference. But I think the problem people have is that we always assume the best for SEC teams and (often) the worst for other teams. Like Ole Miss beat Bama at home, Bama was obviously not playing their best at the time; see: 1 point win against Arkansas a week later. Ole Miss then beat A&M who we now know is trash. So is Ole Miss awesome? Or did they have one really nice win, but isn't really a contender? And so does LSU really deserve to jump 8(?) spots for beating them? Especially when they have been getting trashed by analysts all year, Suddenly they are a real threat? Weird.
Or like Oregon, they lost to what we now know is a really good Arizona team, with basically no starting O-lineman. They are STILL trying to recover from that loss. Alternatively, people didn't say "Wow that Ole Miss loss looks even worse now, maybe Bama isn't all that." Instead it's "OMG, LSU is awesome! they beat the team that beat Bama!" What other conference would get that treatment? Bama since the loss has struggled vs Arkansas, crushed A&M, and beat Tennessee. Oregon has crushed everyone since losing, and they lost earlier, which always seems to affect voting (Ole Miss drops behind several one loss teams because theirs is the most recent.). So why does Bama (and Auburn) get to make up the deficit and jump back into the top-3/4 so quick? Have they looked better than Oregon since losing? Do wither of them have a win against a team as good as MSU? I think that's what people mean when they say SEC gets favored.
