Minnesota sports history is filled with extreme highs, crushing lows, colorful personalities, amazing moments and haunting questions of "what if …"
But you would be hard pressed to find a bigger story — one that combines all those aforementioned elements — than the arrival of Brett Lorenzo Favre with the Vikings.
The quarterback swoops into town on a gorgeous summer Tuesday, setting off a frenzy, and signs with his longtime rival — in the year he turns 40, after being cut, no less. And then he takes the Vikings within a whisper of the Super Bowl? Then it all falls apart, and his old team wins the Super Bowl without him? You couldn't write a more compelling script, and that barely scratches the surface of what happened.
Sunday is the 10-year anniversary of the day Favre arrived at the Vikings' former training facility in Eden Prairie, with a helicopter, media members, fans and even a guy in a parrot suit giving chase. Yes, it really has been 10 years.
The Star Tribune's Michael Rand spent the summer constructing an oral history of Favre's arrival, and all that came before and after that day unlike any other. All interviews were conducted either in person or on the phone except with Favre himself, who responded to questions via e-mail.
Hold on tight. It's a bumpy ride.
The build up

BRAD CHILDRESS, former Vikings head coach: If you go back the year before that, I remember having a conversation with [Eagles] coach [Andy] Reid when they beat us in the playoffs and he said, 'You know, if you get your quarterback thing straightened out you have a hell of a football team.' I wanted to say, 'It's not for not trying.' I mean, from Tarvaris Jackson, Kelly Holcomb, Gus Frerotte and you could probably fill in all the other ones, we traded for Sage Rosenfels. But anyhow, it was all about getting that position right.

SAGE ROSENFELS, starting QB candidate before Favre arrived: I really worked a trade and probably sort of burned some bridges in Houston that February or March to get to Minnesota to compete with Tarvaris to be the starter. It was really the first time in my career I really had the chance to even be the starter. I had always been the third guy or second guy leading up to that point. I had played a lot in Houston and played pretty well. This is really my big shot. I took some risks to go up there and try to have a shot at being a starter. I knew at the very worst I'd be the backup if I lost out to Tarvaris.
