As previously mentioned on this site, this year is looking more and more like 2010, when there were between 8-12 teams who were pretty darn good, and everyone else pretty much sucked in different capacities. That's relevant here because deciding how much different teams suck is a lot of the battle in creating a poll. If you want mathematical/statistical evidence, look at the pattern in SD (standard deviation): the top 7 have a relatively small standard deviation, where it just explodes after that.
Now I'm curious, readers. Who is duping us all, looking good but is actually pretty crappy? Who is a lot better than they look right now? Who is going to be surprisingly good at season's end?
