Max Harvat's heart was pounding when he got down on one knee in a Nashville hotel.
It only got worse when Harvat -- a Panthers fan -- identified the 6-foot-5 stranger recording his big question.
"Oh my god, you're my hero," Harvat said to Olsen after the proposal. Then, it sunk in.
Harvat followed the Panthers as a kid growing up in Pennsylvania, according to Bryan. Now its star tight end was recording his life's biggest moment.
Said Harvat: "I'm a huge Carolina fan. I was like, 'Oh my God, you're telling me that Greg Olsen just recorded the whole thing?' I was so excited."
That feeling was clearly mutual. Olsen excitedly asked what the future Mrs. Harvat's answer was, and when he found out, he cheered like he knew the happy couple forever.
"She said yes and I got it all on video, and you don't even know me, but I'm going to send it to you," Olsen said. "It's the best thing I've ever witnessed."
