AJ Brown for Thielen

I am loaded at WR, so I wanted to upgrade. I know Brow is out for a bit, but I can wait.
WR are now: K Allen, DJ Moore, Godwin, AJ Brown, AB, R. Moore.

with all those WRs would you be better off flipping brown for a RB? Either way, I like Thielen over Brown but I will admit I have been skeptical of Brown all offseason so I am probably biased
