Stupid tweet. If they added Iowa State the SEC would have an even larger share. It proves nothing and only shows their bias. Also, if they left out TX and OK then the SEC would have even less AA's. WOW!! Really? if you add more you get more? And if you don't add anymore you don't get anymore?
In the B12, TX and OK were big fish in a small pond that allowed OK to feed on the smaller fish (not TX, because they suck) and get bigger. In the SEC, TX and OK will be big fish in a slightly larger pond full of big fish. They will not have the advantages of before.
Not to get long winded, but what I am attempting to say, is that, the SEC will probably only get a marginally larger number of AA's with the addition of TX and OK. It is not as simple as add or subtract. There are much larger statistical and social complexities involved. Dennis Dodd should be ashamed of putting such stupid information out there.
