Well, yes. Seeing as how on a team's bye week, the entire team (offense, defense, special teams, cheerleaders, hot dog vendors) doesn't play, you should invest in another def and k for the week, maybe drop a bench player to pick up a fill-in defense for the week. It would be a miracle if the San Diego defense, or any defense for that matter, would score you any points on their bye week. You have a better chance of not seeing Brett Favre in the news than having your defense score on their bye week. In other words, bench your usual defense and pick up a filler for that week.
