Welcome to Favre country

Posted by ESPN.com's Bill Williamson

EDEN PRAIRIE, Minn. -- As I scrambled from the Kansas City Chiefs' camp in River Falls, Wis. (my deepest apologies, Chiefs fans, I will return to Kansas City's camp Wednesday) to the Vikings' headquarters, I realized I hadn't been there for five years.

I forgot my exit.

But thanks to the hovering helicopters and satellite trucks camped out, I soon realized where I needed to pull off.

Welcome to Favre Country.

Suburban Minneapolis was the NFL's epicenter Tuesday. Fans hung around the Vikings' practice field for no other reason but to just say they were there the day Brett Favre became a Minnesota Viking. A nearby restaurant had its name covered by a sign. It now reads "Favre Café."

The media was abuzz when the graying, soon-to-be 40-year-old legend walked out on the lush practice field, wearing a red No. 4 jersey, purple shorts and a Vikings helmet.

Just as Brett Lorenzo Favre was signing his one-year deal with the Vikings, backup quarterback John David Booty was searching for a new number. Wearing No. 4 until Tuesday morning, Booty is now No. 9 in Minnesota.

Yes, it has all changed.

Minnesota quarterbacks Sage Rosenfels and Tarvaris Jackson -- who until Tuesday were in a battle for the starting quarterback job -- were watching Favre take repetitions. There even appears to be a chance Favre will start Friday night's preseason game at the Metrodome against Kansas City. Believe it, NFL, Favre is back.

I will shoot back with post-practice reaction. Favre is set to hold a press conference at 6 p.m. ET.
