I think if the Vikings have a QB who doesn't turn it over or make stupid throws, they'll be a force this year.
If Brett comes back, he stands a chance of going 0 - 2 against the Packers and finishing on a bad note either way.
Brett is 2 - 0 against the packers, had his best statistical season and was in the NFC Championship game within only three points of winning before overtime.
I think now would be a good time for him to retire, for himself.
I'd like to see him come back and the Packers beat the Vikings twice and Vikings finish at or below .500, that's just me though. You want to be the best, you have to beat the best. Right now, Vikings are the best in the division with Favre, that's what I want to face, that's what I want to beat.
