Capacity absolutely matters when you're talking about big-game environments. Auburn's Jordan-Hare holds 88,000 and has sold out 127 consecutive games, so the "half-empty" argument doesn't apply here. That consistent sellout streak creates a sustained decibel level smaller venues can't match. The stadium's size directly translates to home-field advantage, with opponents averaging nearly 2 more penalties per game due to the noise. A packed 88,000 creates an intimidation factor a packed 25,000 simply cannot replicate.
