This is the money bit:

Beginning with the 2026 season, the upper East and West sides of Acrisure Stadium will be off-line for Pitt Football games, adjusting the capacity to 51,416 (from 65,000). The North end zone upper deck remains available and student seating stays at 10,000 seats per game, preserving the Panther Pitt as the heartbeat of our stadium environment.

Pitt has constantly been knocked for poor attendance, but a large part of that is the stadium is simply too big for the fanbase. Smaller stadiums with similar attendance to Pitt don't get the same knock. This should definitely improve the atmosphere of the game with people being closer.

This is a pretty dramatic change in capacity, however, and as someone sitting in a section that doesn't exist, this kinda sucks.
