At this point I can hear the whispers of the Tide fans, all of them saying, "You know, I don't always agree, but I can't wait to hear Bill's analysis of this question."
So here goes.
First of all, throw out 2007 - most of those were not even CNS players, which is not a dissing. Note also we were 6-2 when the Textbook Scandal took all those players off the field. So let's look at each year:
2008
Record: 12-2
Home: 7-0 (Big wins: Auburn)
Away: 4-0 (Big wins: Georgia, LSU, Tennessee)
Neutral: 1-2 (Big wins: Clemson, big losses: Florida, Utah)
VERDICT:
Problem analyzing because there weren't really any big games at home. We played mostly soft touches at home, so OF COURSE the big wins would be on the road.
2009
Record: 14-0
Home: 7-0 (Big wins: S Carolina, Tenn, LSU)
Away: 4-0 (Big wins: Ole Miss, Auburn)
Neutral: 3-0 (Va Tech, Florida, Texas
VERDICT:
I think home gets it this year because those three games were in consecutive games (with an off week prior to LSU). The Tennessee game was THE best example of rising to the occasion at home, but the Auburn win was a great example on the road. This particular year we were deadly in neutral site games against ranked teams, winning by scores of 34-24, 32-13, 37-21.
2010
Record: 10-3
Home: 6-1 (Big wins: Penn State, Florida; big losses: Auburn)
Away: 3-2 (Big wins: Arkansas; big losses: S Carolina, LSU)
Neutral: 1-0 (Big win: drilling Michigan State)
VERDICT
What is hard to take into account is the effect of all those consecutive off-weeks other opponents had. South Carolina beat us right after the emotionally charged rout over Florida. LSU beat us after an off week - but we both had an off week. Needless to say, the most painful loss had to be against Auburn. That one was so bad that I'd call this year a wash.
2011
Record: 12-1
Home: 6-1 (Big wins: Arkansas, big losses: LSU)
Away: 5-0 (Big wins: Penn State, Florida)
Neutral: 1-0 (LSU)
VERDICT
OK, the problem evaluating this is that the so-called neutral site game was - in reality - an LSU home game. No, it wasn't at Tiger Stadium, but it was in their state close to their place and they had more than half the tickets. Because of that and the sting of the November loss, I'd give this year to the AWAY games.
2012:
Record: 13-1
Home: 6-1 (Big losses: Texas A/M)
Away: 4-0 (Big wins: LSU)
Neutral: 3-0 (Big wins: Michigan, Georgia, Notre Dame)
VERDICT
The sheer emotional swings of LSU on the road followed by the aTm loss again point this one in the direction of neutral site games, where we drilled two top ten foes and edged a third one.
OVERALL DATA SINCE 2008
Record: 61-7
Home: 32-3, .914
Away: 20-2, .909, but .913 if you count 2012 BCS title game as road
Neutral: 9-2, .818 but with a current eight-game winning streak
VERDICT
I don't think there is any SIGNIFICANT difference. The percentages are basically the same, especially if you count LSU as a road game in the BCS title game.
These are what the data show. My initial thought was in favor of the road. It may be a VERY SLIGHT edge to the road, but it is miniscule.
