Trade Marlon Mack?

Good morning fellow BallerClan.

Question is, I have Marlon Mack and in a standard league with only 1 flex (2 RB, 2 WR)…would you trade Marlon Mack away to get Michael Thomas?

I already have: RB’s: James Connor, Kerryon Johnson, Chris Carson, Devin Singletary. WR’s: Davante Adams, Julian Edelman, Robby Anderson, Michael Gallup, and Evan Engram.

Thanks, and looking forward to the advice!
