Three general rules:
1) Do not schedule any Alabama opponent a conference game the week prior to their game with Alabama (only something like five times in the last three years, including this season, has a team have had to play Alabama the week after another conference game - something that only happens once I think this year (Tennessee versus Miss State).
2) Schedule a conference game for all Arkansas opponents the week prior to their game with Arkansas (something that happens six times this year I believe).
3) Schedule all other teams with a balanced list of opponents who play conference games the week prior with those who do not.
Pretty much sums things up.
