CB question

Our league is CB required league. Option is

T Lipplet vs Pit or S Smith vs KC:

T Lipplet has been tackle machine once X Howard is off due to injury. With Benwikere signing, can Lipplet be benched? Otherwise, Big Ben will have a field day with X Howard and R Jones possibly out. T Lipplet will have an ample opportunity for tackles.

S Smith has been targeted by opposing QBs. For the same reason, I wonder he could be benched. Chiefs will run the ball whole day with J Charles healthy, which could limit tackle opportunity for opposing CBs.

Smith really hasnt been that fantasy relevant throughout his career and I don't see him getting many opps in the game against KC this week. Lippet has more upside IMO. He played 92% of the snaps last week. Doesn't sound like Benwikere is going to start "any time soon."
