I know most of us here already believe that the SEC is overhyped, and that ESPN has a lot to do with the "strength" of the conference. It has been discussed time and again on this site.
A buddy of mine shared this article with me while I was watching the BCS NCG on Monday night. This is probably the most well thought out position I have seen on this matter. It may have come up at some point in one of the Slates (it IS, after all, over a year old), but I wanted to share the link here in case people haven't seen it.
This goes along with the "but aTm and Mizzou were middling teams in the Big 12, and in their first two years of SEC membership, each has done pretty spectacular things. Wonder if that might be because the Big 12 is actually a stronger conference than given credit for (or maybe the SEC isn't quite as strong as people say it is). And TCU and WVU were blowing their opponents away when they were in other conferences, yet have lingered in the bottom half of the Big 12 since joining." argument. But you'll never hear anyone on ESecPN say anything to this effect.
