I haven't followed this thread closely, mostly because I don't care what the scheduling in the SEC ends up being, and also because I tend to ignore threads when I see they have devolved into a pissing contest between posters. Which means I end up ignoring most threads after the first couple of pages.
However, the above statement caught my attention. I was curious if the assertion about LSU is correct, so I went to the Texas page on Winsipedia to see.
Not counting the schools in black that Texas played back in the 19th century or during WWII...I guess LSU is the second most played team behind Tulane that has never been a conference game. Or 3rd most played if you count the majority of OU games that were OOC before the formation of the Big XII.
I don't know about the 5 or 6 SEC teams claim on your part, though. That would take more research than I want to undertake right now. You maybe right. Or not. I am going to go out on a limb and say you are either right or wrong about that.
