Struggling on this Mostert trade offer

Hi guys

In a full PPR league I have a trade offer of Drake and J Kelley for Mostert and Anthony Miller. I would be giving up Mostert and Miller. It would leave me a little light at WR but still have AJ Brown, Woods, Fuller and jeudy. What do you think? My RBs are

Elliott
Ingram (tried to put him in deal instead of Miller but no go)
Hunt
Mostert
L Murray
Gibson

I think dumping Miller is a smart move. You are getting a slight upgrade from mostert with drake, but PPR makes it a lot closer. I think it comes down to if you think kelly with be almost what mostert is. I would probably accept the trade.

Great, thanks
