Need help! David Johnson trade!

Offer: DJ for DK Metcalf .

Bench: David Montgomery, B. Snell, AJ Brown, Kenny Golladay, Jarvis Landry,

What do you think of this 1 for 1 trade? Should I accept it. I believe that another WR and different QB2 would make my team a contender. Let me know your thoughts. Thanks in advance.
