Offered McCaffrey straight for David Johnson. PPR league. Backs are DJ, Tevin, Cohen, Lindsay
That's tough. I think I'd keep DJ though. He has an insanely easy ROS schedule. I think McCaffrey's best days are behind him unless Greg Olsen gets injured again.(lowers his pass catching volume)
DJ has multiple TD upside every week. A McCaffrey TD will be rare. If Mike McCoy starts using DJ a little bit more creatively I could see you really regretting that trade, but that's certainly not a given I guess.
McCaffrey comes with the safer floor if nothing changes with DJ's usage, but I wouldn't shoot for the floor with my RB1 when you're going to be facing off against teams with Gurley, Barkley, Gordon, etc in the playoffs. It's hard to envision a scenario in which you win your league with McCaffrey as your RB1 imo.
