Missy Franklin didn’t expect a thing.

In fact, last Friday, she almost didn’t come to school.

“It was the assembly for the senior gift giveaway,” Franklin said. “I had absolutely no idea that anything was going to happen. I was even thinking about not going to school that day — so my best friend and my mom had devised this whole plan to make sure that I was at school.”

But the Olympic hopeful was in for quite a surprise.

First, she was called up to the front of the assembly, bringing raucous cheers from her classmates.

Then came the big one — Broncos wide receiver Eric Decker entered the room to wish the swimmer luck.

“I had to be here,” Decker told the crowd. “On behalf of the Denver Broncos, I came here to wish her the best of luck this summer, and you better bring back that gold for us. Good luck!”

If the cheers were loud before, they were deafening when Decker arrived.

“I was so shocked,” Franklin said, mentioning that she had met Decker once before at the Colorado Sports Hall of Fame banquet. “As soon as they said his name, all of the girls just went crazy. Eric Decker in a room with 1,000 teenage girls? It just doesn’t get louder than that. I was so excited to see him. I was so happy he was there. And that was honestly one of the nicest things that anyone has done for me. For him to come and take his time right before he had a flight, to come and just say a few words, it meant the world to me.”

Franklin, who is a “huge Broncos fan,” said Decker’s presence even caused a few classmates to bend school rules a bit.

“It’s really funny, my mom was laughing because technically at school our phones are supposed to be in our lockers,” she said. “But she said as soon as he walked in, 500 phones just snapped up to take pictures and video.

“It was great.”
