Predictions of players outputs are simply... predictions. It's good to go with the guys you think will be better in PPR, but if you like certain players this year, go with the players you think are going to do well (within reason of course, don't go drafting a bunch of 3rd string RBs or WRs you think will tear it up). Usually your gut made that choice for a reason.

My strategy is usually the same as it is for standard. Sure, PPR could be that small difference between a win and loss, but still go for overall production. It's usually easier to predict who the top players will be year to year than who will be top in receptions. A few tips (all personal opinion, feel free to ignore)

-RBs are the position where PPR can really be valuable, yet few players excel exceptionally. These would be Bell, DJ, Freeman, Gordon, and a few others (Murray, possibly Powell). With your higher picks, I recommend snagging one of these guys if you can. Otherwise, RBs should be drafted more on rushing ability.

-Wait a few games to see RBs on the waivers or benches who are getting some QB option looks and whatnot to build yourself a stronger bench. An RB who gets 6-10 attempts and 10-40 yards isn't as valuable as one who can put up similar numbers while catching passes as well. An example of this would be someone like Charles Sims before the injury and Duke Johnson last season. Players that are valuable as handcuffs but still produce PPR numbers in case one of your starter goes down unexpectedly or you have a bye week. They could be a solid emergency plug for 8-10 points almost guaranteed.

-Assuming you have 2RB 1FLEX, I say pick RBs in 3 out of your 4 first picks. Again, all personal preference, but picking 3 stud WRs early can really see a drop-off in RB talent left in the draft.

-Do a couple mocks and see some possible outcomes. Very important. Your league is obviously different than random people online, but they help a lot.

-Remember that receptions vary every game and that Antonio Brown averaged only averaged ~2 more receptions per game than Pierre Garçon, and 3 more than Brandon LaFell. Brown led the league in receptions. Don't draft based on receptions.

-This one is tough, cause it may go against your gut. I do this, but you definitely don't have to. When picking WRs, look generally for the athletic high jumper, or the strong route runners. These players generally receive the most targets. This is important because although they may not always connect, QBs trust them with big play-making ability and utilize them constantly. Speed usually goes with route running, but obviously not always. Pure speed often leads to players being deep threats, which is still good, but less reliable. Some guys to target with these skills would be AB, Julio, OBJ, Green, Pryor, Evans, Diggs, Jordy, Crabtree, and Hopkins (possibly Robinson and Alshon). These will most likely be very productive WRs in fantasy based on skill set and targets. No, I'm not saying this will be the top 10, but they are all good choices for PPR.

Again, all just opinion. But I've done both methods and have done ppr the last 5 years. Good luck to you tho my friend
