How quickly we forget how ridiculously good DJ is. When it comes to a player with that type of talent and workshare (especially considering how good and involved he is in the passing game - remember OP stated this league is full PPR), the team situation just doesn’t bother me that much. He’s already produced, at about as high a level as is possible, on a bad team. McCoy has done the same for years, and DJ is every bit that good from a talent stand point.
Seriously, look at what he did on a sub .500 team 2 years ago: 1239 rushing yards on 293 attempts, 80 receptions for 879 yards, and 20 total TDs. If you’re counting, that’s 411 points in PPR, which would have been 1st overall in PPR this year by nearly 30 points. Take away, say, 20% of the yards and receptions and 50% of the TDs (because 20 is obviously difficult to replicate), and he’s still at 335ish PPR points, which would have been good for 3rd at the position this year.
But to be honest with you, I think the receiving numbers are going to go up. He may well be the best receiver on the roster this season. Throw in the workload he’s going to get rushing, even if it’s relatively hard sledding, and you have about as safe a floor and as high a ceiling as any RB around.
As for ‘injury prone’, every RB not named Frank Gore is injury prone, and DJ no more so than most, including Bell. A hand injury doesn’t concern me for an RB at all.
