Help: Too many starters in SF-LAR

I feel like I’m playing against myself this week, and need to know if I should pivot away from a starter or two. I’m starting the Rams defense because I think they will fast in the SF o-line. Also playing Kupp at WR. Confident in both of those choices.

However, I’m also starting Kittle and Mostert (flex). I can pivot to Jonnu Smith at TE.

Chark, Hollywood, and Higgins are riding my bench and could replace Mostert in the flex.

Would you make any changes, or should I stand pat with the two 49ers?

Kittle is an every week start. He comes out your starting lineup for injury or bye weeks only.

Mostert took back over as the team RB1. I see no reason to question his inclusion in your starting lineup.
