Should we rest starters ?

I’m sorry but am I missing something here?
The Niners/Seahawks don’t play until Sunday night so why in the world do you rest your starters and risk losing? You lose against the Panthers you have no chance at a bye.
We can lose @ Carolina and still have the 2. it ALL depends on Sf @ Sea. Also think about 6 see Minnesota resting starters this week because they cannot improve seeding at this point, so they are on a "bye" . Yet we could go into that game battered.
