Take it from a guy who has gone to many college and HS games at all three, has lived/worked in two of the states and traveled/vacationed some in the other, and has good friends in all three - the order is:
Arky
Ole Miss
Mizzou
FWIW, some of you are probably not aware that the Arky/Ole Miss rivalry runs deep and goes back to when Arky was in the old Southwest Conference. They played in Little Rock and Jackson in alternating years. Arky has just been messing around with doofus coaching hires since Petrino blew himself up. Frank Broyles, Lou Holtz, Houston Nutt, Petrino - they've had some guys that could win and make opponents miserable on Saturday over the decades. If Kiffin could stand the "wooooo, pig, sooey" stuff he would do well there.
