In case your television, internet, radio and phone/mobile device were all shut off on Tuesday, you've undoubtedly heard by now that ageless wonder Brett Favre has decided to come out of retirement... or, perhaps more appropriately, stay unretired for another season.
After being harassed by three teammates in Mississippi on Monday, Favre flew to Minnesota and wandered into the training camp of the Vikings just in time to ruin Tarvaris Jackson's summer. The only active grandparent in the NFL will be under center when the Vikings open the regular season against the Saints in prime time.
So what is the fantasy impact of Favre's return?
Adrian Peterson's value just went through the roof. Without Favre in the purple and gold, Peterson would have been a marked man all season, facing a lot of eight and even nine-man fronts as every team in the league would undoubtedly beg Jackson to beat them. Now that Number Four is back, opponents' secondaries will have to respect Favre's arm.
Sidney Rice just moved back from a third-tier receiver into a strong WR2 play and even perhaps a WR1 play in a deep league. Bernard Berrian could also see increased production, especially in any absences from Percy Harvin. Visanthe Shiancoe's value also skyrocketed with this news.
Jackson has no value now, and Favre should be considered a strong play in any format. However, expecting Favre to duplicate his career-best numbers from 2009 would be foolish. Remember, too, that Chester Taylor is in Chicago now, taking the Vikings' third down back of choice and more reliable fourth quarter back out of the mix.
