since I'm bored and a homer I might as well argue against the AP MVP case, since I just realized something. The major factor in the AD case is that he was the reason his team was winning and without him this team would likely be 3 or less win team. Well in the first 5 weeks the Vikings went 4-1, let's look at AP's stats in those 5 weeks.
Week 1: 84 yards/17 attempts/4.9 average/2 TDs. 26/23 Vikings win
Week 2: 60 yards/16 attempts/3.8 average/0 TD. 20/23 Vikings lose
Week 3: 86 yards/25 attempts/3.4 average/0 TD. 24/13 Vikings win
Week 4: 102 yards/21 attempts/4.9 average/0 TD. 20/13 Vikings win
Week 5: 88 yards/17 attempts/5.2. 30/7 Vikings win
also week 16: 86 yards/25 attempts/3.4 average/0 TD. 23/6 Vikings win.
Clearly he wasn't the only reason they were winning.
