Nope, Madsen’s more like a wild stallion—graceful, untamed, and impossible to rein in. The guy’s putting up video game numbers this season: 2,714 yards, 22 touchdowns, and only three interceptions. Oh, and his touchdown-to-interception ratio? A ridiculous 7-to-1.

That’s one of my favorite things like sitting there and being able to watch her and support her. I have never been a soccer fan like that so, it’s now fun for me to go crazy over the bodies,” Madsen turned out the biggest cheerleader of his girl.

”We knew each other from high school and how we always look back at like these big dreams that we had for ourselves and kind of how we are living it together,’‘ said the Broncos QB with a shy smile in his eyes.
