So who's ground attack will win the game for the niner or vikings?

What do you think? Adrian Peterson by far one of the best runners in the NFL vs one of the most improve defenses in the NFl? or Frank Gore vs Minn def who cant seem to stop the run? But the vikings do have BRETT damn this is tuff but i believe the NINERS come out with the win this sunday cause of their defense. WHAT DO YOU THINK
