Trade my Alvin Kamara in Dynasty?

Hi everyone. Should I trade or hold onto Kamara in a 12 team Dynasty league? It is a full ppr league.

I’m not definite on wanting to trade Kamara but if I do, I’m thinking of offering Kamara for Devin Singletary, and this year’s 1.04. Is that a good trade or should I see about trading Kamara in a better deal?

Should I wait until after the NFL draft before making a trade? Buffalo may draft an rb?

I’ve also seen online someone saying Kamara might be traded.

I don’t have any 1st round picks this year.

My other rbs are Mack,Hines, Justice Hill, Breida, John Kelly, Wayne Gallman.

Any help/advice is appreciated😊, thank you.
