Defense Quandary

i’m in a 12-team standard league with only four bench spots this is my current team:

QB: A Rodgers
RB: Lev Bell, K Hunt, Carlos Hyde, Javorius Allen. Rob Kelley, Chris Johnson
WR: D Adams, M Bryant, R Cobb, R Higgins
TE: Eifert
K: Succop
Def: KC (@ LAC this week…)

I don’t really want to play KC Defense against the Chargers but I also don’t want to drop them. Should I
drop another player to pick up another defense for the week? Packers, Bucs, etc. or just play the chiefs?

Personally, I’d just drop them if there is a better matchup on the waivers. I drafted Seattle defense and dropped them before the season to take a flyer. I feel like you have a better chance of hitting on a high defense score by streaming matchups than rolling the same one out there each week.
