One of two things is happening right here: You're either an idiot talking out of his ass, or just flat-out retarded... personally I think it's a little bit of both, but don't worry, I'll keep it our little secret...
To say they'd still be a playoff team is just stupid. You've obviously watched little to no Vikings football this year, because Favre has CARRIED this team on his shoulders and made EVERYBODY around him better. Adrian Peterson is still a great running back, but he has NOT been the same Adrian Peterson of last year or the year before. Look at it this way... defenses have OBVIOUSLY had to key more on the Vikings passing game this year than last year.. last year they knew if they stopped AD, they stopped the Vikings offense flat-out... this year Favre comes in and has done what he's done, which should have opened up the game even more for AD since defenses have to pay more attention to Favre... so what has AD done? His yards per carry have gone DOWN not up, and he's already managed to lose more fumbles this year than last. Had Jackson been the QB this year, Peterson's stats wouldn't look NEARLY as good as they do now, since defenses would've been able to key on JUST him and clearly something just aint quite right with his game this year... like I said, he's still a top 5 RB in the NFL, but without Favre, there's not a chance in hell he'd have 12 TD's and over 1,000 rushing yards already...
AD has had 3 big rushing games this year... against HORRIBLE Cleveland, awful Detroit, and Baltimore (thanks to busting off a 60 yard run).
Against Chicago this past week and Seattle the week before, he managed a total of 3.4 yards per carry, and each of those teams ranks toward the bottom of the NFL in run defense, giving up an average of 4.3 YPC... and its not like they gave up on him and just let Favre loose, he carried the ball a total of 49 times in those two games...
Brett Favre is the reason the Vikings are 10-1 and battling for home field throughout the playoffs... they would NOT be a playoff team without him this year, with Adrian playing the way he has. Favre already has more TD's thrown this year than all Vikings passing TD's COMBINED last year from Frerotte and Jackson... the Vikings had several things come together just right last year to BARELY make the playoffs, thanks to their D, AD, and a stretch of decent play from Jackson, and you saw where they went once they got to the playoffs.. to say the Vikings would make the playoffs this year without Favre, I think is sadly mistaken.
