Brett Favre enjoyed his time with the Vikings this season, but he's still unsure of his future. "When I decided to return to the NFL to play my 19th season, I did so with some trepidation," Favre told OfficialBrettFavre.com. "After all, I was joining a new team in a new city, for the archrivals of the 'green and gold.' And I'm not getting any younger. "I couldn't be happier about my decision. The coaches, staff, and especially teammates who joined me in the season's journey are true professionals, and better yet, friends. I felt completely comfortable from Day One as a member of the Minnesota Vikings, and it's a tribute to the entire organization that accepted me with open arms." Favre then thanked fans that have tried to convince him to return to the Vikings with billboards.
