Nihilist Football Picks: Pro Week 4/College Week 5

I had another good week last week, going 2-1 in both college and pro picks. The Irish and Vikings conspired against me, though. This week I like:

College:
Notre Dame -12 at Purdue
Michigan -20 vs Minnesota
Arizona +12 1/2 at USC

Pro:
Vikings -2 at Chiefs
Falcons -4 at Seahawks
Lions +2 at Cowboys
