I'm starting both in my league luckily!
The Viks secondary isn't too strong against the pass so Jennings will see touches. Rodgers tends to target him a lot and he has been producing for me. He did well in my league against the Viks last time as well.
Bowe on the other hand has more points in my league and against a weak pass defense that allowed Hasselbeck of all people to throw 300+ I'd say he is a viable option. It really depends on how well Arizona stops KC's run. If KC has to resort to passing again Bowe will get mass points like last week.
