Mostert value? WR trade

Half PPR 10 team league.

RB: Henry, Mixon, Montgomery, Gibson, Kelley, Hines
WR: Golladay, Cooper, McLaurin, AJ Brown, Deebo, Lazard

I feel weak at RB given that Mixon (and Henry to an extent) are underperforming.

Hes weak at WR and wants Golladay, but I’d prefer to give McLaurin. Settle on cooper?

What’s a good trade?

He will take AJ Brown and Gibson for Mostert… is this worth it?
