Know when to hold them and when to fold them.

1 PPR 10 team league
Currently 0-2 and losing confidence in my bench filled with decent backup RB’s. Just how it fell out in the draft for the reason i have them. Thinking i need some better WRs. If trends continue, which players would you drop in order of worst to best? Should i wait a couple more weeks to see if they can do better or possibly try to trade while their stock hasn’t completely tanked?
TIA
