Montgomery + OBJ for Jacobs OR Carson

10 team standard league.
Trade would be a 2 for 1, with my team receiving the Monty/OBJ combo.

My current team is
Cook / Carson / Jacobs / Michel / Singletary / Mattison
K Allen / Kupp / AJ Green

I feel like now is a good time to buy those 2 players, but is it worth losing either Carson or Jacobs, and who would be better to trade away? The other owner is currently deliberating but I believe he’d rather Jacobs based on schedule. Not knowing how Green will come back, I’d like another WR and downgrading slightly at RB seems like a fair move.

Any thoughts are much appreciated! Cheers.
