Here is what I got first:
“Historic Night in Salt Lake City: Record-Breaking RES Crowd Witnesses BYU’s Triumph Over the Utes—Largest Gathering Ever at Utah’s Own Stadium to See the Cougars Claim Victory!”

Or if you want to lean even more into the hyperbole:

“Unprecedented Masses Flock to Rice-Eccles Stadium to Witness BYU’s Dominance—No Greater Crowd Has Ever Assembled to Watch the Utes Fall at Home!”

Or a bolder take with a playful jab at the crowd size:

“RES Reaches Full Capacity—But Not for the Utes! Record-Breaking Crowd Sees BYU Claim Victory, Making History in Utah’s Own Backyard!”

Then I asked for more gloating and got the following gems:

1. “Crowd of the Century Gathers at RES for BYU’s Glorious Victory Over the Utes—Never Before Had So Many Witnessed a Utah Defeat!”
2. “Utah’s Largest Stadium Crowd in History? All Just to Watch the Mighty BYU Cougars Silence the Utes in Their Own House!”
3. “RES Bursting at the Seams as Thousands Witness BYU’s Heroic Conquest—Never Has Utah Packed More Fans in Just to See a Cougar Win!”
4. “Historic Utah Stadium Records Broken as Thousands Pile In… All to Witness BYU’s Unstoppable Takeover of Rice-Eccles!”
5. “Record-Setting Utah Crowd Shows Up Expecting a Victory, Leaves Witnessing BYU’s Legendary Takeover in the Largest-Ever Ute Defeat!”
6. “Utah Fills RES to Capacity, Only to Watch BYU Make History as the Greatest Crowd Ever Gathers… to See the Utes Fall!”
