Chris Carson for next year 1st pick

In a Super/Flex IDP 3 starting RB league (There’s a lot to this league),

I am being offered Chris Carson for my 1st pick next season. Knowing I am in a rebuild I am having a hard time with this trade offer as I don’t see my team being that great this season. Starting QBs if curious are Dak and Fitzpatrick so I know QB needs to be addressed next year.

My current roster of RB’s are
David Johnson
Rashad Penny
Malcolm Brown
Mark Ingram
Deejay Dallas
AJ Dillon
Kenneth Gainwell
