Superflex Blockbuster Trade Help

Superflex Standard Leage

My Team (I trade away)
Deandre Hopkins
Matthew Stafford
Royce Freeman

His Team (I get)
K Johnson
Joe Flacco barf
Travis Kelce

Help! I have Darren Waller right now as my TE and D Watson & Jamis as my QB and Superflex. After this trade my WRs would be Kupp and Boyd (Mike Williams on the bench). Don’t love where that leaves me RB wise, but is the kelce / KJ deal worth it?

Thanks guys.
