Dynasty Trade Advice Needed! Royce & Gallup for Picksss

I own Royce Freeman & Michael Gallup in a 3WR standard scoring dynasty.
I’ve been offered a 2020 1st, 2020 2nd, 2021 2nd & LeSean McCoy for them.

I’m so stacked at WR but incredibly weak at RB. Won’t win this year but could make a push next as already have 3 x 2020 1st rounders

Do I trade away Royce Freeman (and Gallup)?

Thanks all
