The total has been hammered down by the presumption that, because the teams use mirror triple-option attacks, the defenses’ familiarity with them will lead to a low score. Yet an Over/Under rarely gets as puny as this one. Collectively, the teams score 58.3 points a game, and the Eagles’ last outing produced 78 points. Look for the Eagles to throw more than their average of 10 times against a suspect pass defense.
