Looking at FBS competition only...
The Aggies are scoring 63.2% more than their opponent allows, which is impressive to say the least. The problem is their allowing 13.9% more points than their opponent normally scores.
Auburn is currently scoring 12.5% more than their opponent allows, while their defense is holding their opponent to 31.7% below their scoring average.
Taking A&M's average score vs. Auburn's scoring margins and it projects a 37-30 Auburn victory.
Taking Auburn's average score vs. the Aggies scoring margins and it projects a 36-33 Aggie win.
Average the scores and Auburn wins 35-33.
Based on FBS averages and current yardage margins, it projects Auburn to have 504-537 yards this Saturday and for Texas A&M to have 554-655 yards.
Two concerns for Auburn, they need to avoid is a slow start and turnovers. The yardage percentages and margins project the Tigers to rush for 297-341-yards. If this is the case and Auburn wins the turnover battle, I see the Tigers coming out victorious.
