I think Bama's starting line up is better but LSU has much better overall depth ie a better team. On paper this should be about as close as you can get, very similar teams, Bama has more bulk on the D but LSU has better speed.
I like LSU's offense, back on track, to me the most efficient offense in the country. Nothing fancy but just getting better every week. Not afraid to go deep, not afraid of running up the middle, not afraid of screens, etc. Stats are deceiving on LSU's O. IMHO
I give a very very slight edge to Alabama based on home field and more upper class-men but boy this seems close on paper.
It might come down to kicking in that case I give a slight edge to Wing as punter, FG kickers about even.
