should i make this trade in my fantasy league (american football?

so in my fantasy football league i have allen robinson in my team and someone has offered me both sammy watkins and lesean mccoy for robinson. im considering this trade mostly due to lesean mccoy. i have three HB's on my team and they are todd gurley, devonte freemen, and eddie lacey. devonte freemen was pretty bad after his hotstreak and theres no gurantee ediie lacy will return to being good and these were risky picks that i made that i somewhat regret. so do you guys think i should do the trade, im not too worried about losing robinson because i have keenan allen currently on bench ( i was currently debating which of these 2 to start) and sammy waatkins is a pretty adequate replacement in my opinion. so what do you guys think. extra question: if i were to accept this trade i would have to get rid of someone on my team, obviously either eddie lacey or freemen, so which should i get rid of if i do accept this trade
