Golden Tate for Christian McCaffrey?

I’m scrambling for a starting RB right now and one of my league mates is trying to trade Christian McCaffrey who’s one of my favorite buys right now because of the Benjamin trade. PPR, my current team is:

QB: Wilson, Cousins
RB: Martin, Mixon, Morris, McFadden, Henry, Lat Murray, Woodhead, David Johnson
WR: Michael Thomas, Dez, Baldwin, Tate
TE: Brate
