Very Confused about Defense

I have Jacksonville playing Seattle at Jacksonville or Cincinnati against Chicago at Cincinnati. I was listening to the footballers (I believe it was the episode on patreon) and they seemed to be all in on Jacksonville. But later in the show they were saying to start Russell Wilson, Doug Baldwin (compared to other receivers mentioned in the question), and Jimmy Graham. So I’m confused about starting Jacksonville, because in my opinion those three players are the only players to start on Seattle’s team. So why would they say start this defense, but to also start Seattle players? They have Russell ranked at 5, Baldwin at 20, and Graham at 2, this gives me no confidence with the jags. Am I safe to start Jacksonville?
