If the Vikings sign Brett Favre, Jackson will most likely spend the season on the bench where he would be watching one of the greatest quarterbacks ever to play in the NFL. I would assume he would learn something from Favre. Maybe that will somewhat solve Tarvaris's inconsistency. It couldn't hurt.
Bernard and Percy
Berrian is great at catching the long ball and Favre has a cannon. They go together like a hamburger and fries.
Harvin has a lot of potential but has some off the field issues. A leader like Favre could keep him in line and help him mature on and off the field. There are many wide outs that have bloomed under Favre, including Greg Jennings, Donald Driver, and Javon Walker. Maybe Favre could add Harvin to his list.
With Favre, our passing game could really improve.
People are always stacking the box to contain AP. When they do this, our receivers are given one man coverage. Favre will take advantage of this and the teams will have to back out of the box. This will lead to more long runs from Peterson and more scoring on offense.
The Vikings had a great defense last year but, I thought they were on the field too much. Favre will be able to take the Vikings down the field creating long drives. This will eat up time on the clock and keep our defense off the field, and, more importantly, keep the other teams offense off the field.
This could be Childress's last season coaching the Vikings, and maybe Bevell’s last season too. If the Vikings sign Favre, I believe they could at least make it out of the first round of the playoffs. If they do that, I believe they will return for another year. Favre could be a good free agent to pick up for Childress and the Vikings.
