Full PPR. Trade Kamara for Fitzgerald and Melvin Gordon?

Full PPR. I was offered Larry Fitzgerald and Melvin Gordon for Alvin Kamara. Currently in first place, pushing for the playoffs. The downside to this trade is that this is a keeper league and Kamara can be kept in the 8th round next year, but Gordon cannot be kept because he was drafted in the 1st round. Should I do it?

QB - Cousins
RB - Bell, Kamara, CJ Anderson, Gore, Montgomery, Conner
WR - Hopkins, Golden Tate, Robert Woods, Pryor
TE - Jimmy Graham, Evan Engram
