You are having a logic fail here. If having it at home helps us, the inverse must also be true - meaning having it elsewhere hurts us. The major geography difference between MS and AL has already been explained in detail here as well. You are simply choosing to be ignore that(very logical) fact.
Want to lose recruits? Let's strongarm the MHSAA into ONLY having championship games in Oxford and Starkville - instead of a way that's fair and equitable to all fans/coaches/teams around the state - and see how coaches in south Mississippi(which is ALREADY much closer to LSU's campus than either State or OM) respond to us screwing them in that regard. Didn't think about it that way, did you?
You are acting like there are targeted recruits out there(in Mississippi) that are being missed on by State/OM and poached to go play elsewhere, which is simply not true. Literally, no other state does as nice of job of keeping hometown talent at home since 2009 - Louisiana is the only competition. So, you want to accomplish what in recruiting, exactly, in this game? If the two of us are already getting all the kids that we go after, how does it help either of us in any additional way? Any perceived advantage you think we gain, we still lose when they visit Oxford...
Outside of geography, Alabama is an entirely different circumstance that you should really quit comparing. That state gets poached at a fairly high level by other programs - namely Florida St, who has a top 5 Al prospect committed this year, after taking #1, #2, and #9 last year. LSU took #6 from them, Georgia Tech #8, and we took #11(Beniquez). Much, much more talent leaves Alabama than leaves Mississippi.
Let me know if you (still) can't tell the difference here:
