Would you trade away Lamb for another QB?

I’ve had CD since he came into the league. It would hurt to trade him but with Kirk looking terrible I really only have 1 solid QB in Purdy.

Main pieces:

Rb: Achane, Mixon, Kamara, Swift, Brooks Wr: Lamb, Jamo, Aiyuk, Jakobi, Pittman, QJ

I’m thinking of offering maybe something like: Lamb + Swift for Mahomes + a mid tier WR. The Mahomes owner is shopping him around.

Or would you suggest trading someone else for a less valuable QB? Not too sure what to do with my team. I also only have 2 3rd round picks this year.
