never heard of that rule before. Not saying that it's not true- but as much as I follow college football, you would think that if that were the case you would see it discussed more. I think Tennessee played all of thier non-conference games at home this year, so I don't think it's a rule.
As far as location, the most convenient Sun Belt road trip would be Louisiana-Monroe. Bear in mind that I live in the Jackson area. It's just down I-20, and takes about the same amount of time to get there as it does Starkville for me. Arkansas State would be most convenient for our fans in Memphis. I think Louisiana-Lafayette may be a fun road trip, and it wouldn't be all that inconvenient. I think I've seen their campus just off of I-10. South Alabama will be an easy road trip- and we actually have that one on the schedule in the future. I also think that Georgia State will be in the Sun Belt before long if I'm not mistaken. I imagine that they play at the Georgia Dome, and that would be a fun trip. I went to MTSU this past year, and it wasn't all that bad, and it's fairly close to Nashville. There are definately some good road trips in the Sun Belt.
