Why to watch
The Lions are a threat to pick up a personal foul, get ejected or be a part of handshake theatrics at any moment. Don't miss whatever they're up to, even if it's self-destructive. They need to gain positive momentum back, sweep the Vikings and then hope a reformed Ndamukong Suh can lead the way to the playoffs.
Inside story
Percy Harvin in the Wildcat and direct-snap situations will present problems, and it will become a bigger part of the offense, especially if Adrian Peterson is still inactive. The Vikings' secondary is woeful right now, and Matthew Stafford will find seams. This could be a big day for Detroit's tight ends.
