Not doing any startups this year, as I've actually cut back on my leagues, but here's a quick list of some values I like based on consensus rankings.
Running Backs
RB12 Joe Mixon - RB is deep right now, so there's no need to reach on Mixon in the top 5, but I'm a strong buyer/holder at this ranking. I think he has a top 5 ceiling. There simply aren't a lot of big backs who have his speed, quickness, and hands. Multiple Pro Bowl potential.
RB28 Kenyan Drake - Atypical frame, but he's a great athlete. Shifty and fast. He catches the ball well and offers unique versatility. From a redraft standpoint, I'd put him in Derrick Henry/Joe Mixon territory, and he probably shouldn't be ranked so far below Henry in dynasty. I'm not sure which of the two is more talented.
OTHERS: I'm a known fan of Chase Edmonds (RB71) and Devante Mays (NR), but those guys are both strictly late round flyers. Mays is currently injured and not practicing, which could force Green Bay to cut him. I still believe there's a chance that he's the most talented RB on their roster. Somebody has to carry the ball in Indy, and with Marlon Mack (RB36) looking a little overrated, I'd probably put my bets on Jordan Wilkins (RB51) and Christine Michael (RB124). Wilkins is over-aged with average speed, but has great quickness and consistently made plays against top competition in college. We all know Michael's story and his inability to stick anywhere destroys any confidence in him, but even after all these years his quickness/burst jump off the screen compared to his competition. I liked Samaje Perine (RB55) as a Shonn Greene/Rudi Johnson type in the draft last year, and with Guice out, he may get a chance at redemption. Minimal upside, but he's probably not as terrible as people think. Penny (RB17), Chubb (RB20), and Kerryon Johnson (RB27) all make sense at those price points. Chubb flashed the least of that trio in preseason week one, but it's early days still.
Wide Receivers
WR15 JuJu Smith-Schuster - It's kind of a Mixon situation with JuJu. He's not cheap and you can understand why people are ahead of him, but he's probably not quite as expensive as he should be. Tremendous rookie production despite limited target load. Young player with WR1 tools. QB situation is muddy long-term, but he should only get better. I'd take him over Diggs, A Robinson, Cooper, and Adams. I think it's possible that he's a better player than Allen or M Thomas, though those guys have multiple seasons of very good numbers. When you look at the 9 year age gap between JuJu and people like Green and A Brown, it becomes a little questionable whether he should be ranked behind them. It depends on whether or not you think his talent is comparable, because he's a lot younger and a lot more valuable if it is.
WR26 DJ Moore - Not dirt cheap, but not really expensive either. You look at the names around him on the ADP sheet and they're either fading stars, inconsistent enigmas, or mediocrities for the most part. Moore as your WR3 in dynasty is appealing, as he can quickly jump up into the WR2 value range with a solid rookie season. I like what I've seen so far in training camp and preseason clips. He needs to be a little better about winning the contested passes, but his athleticism is going to cause problems because he has a rare combination of speed, power, and quickness to uncover.
OTHERS: John Ross (WR61) looked like a bit of a one trick pony coming out of Washington and had a forgettable rookie year, but let's not write him off just yet. He has elite speed and was a dominant playmaker in college. If he has even a 50% chance of being the next DeSean Jackson then he's a steal at this price. I'm not totally sold that Michael Gallup (WR46) is going to stick, but he has some similar qualities with other early-impact WRs like Michael Clayton and Hakeem Nicks. At this type of price you're not breaking the bank to get a guy who could be a FF WR2-WR3.
Tight Ends
TE17 Eric Ebron - Quietly put together a decent 2017 after a slow start. He's still young and a new team with an upgraded QB might be what's needed to unlock his full potential. Low risk with a high floor and a high ceiling. Even if he doesn't improve, you have a decent backup FF TE. His ceiling is finishing top 6-7 this year.
TE20 Hayden Hurst - Massively underrated. Advanced age for a rookie, but all the tools are there to be a steady top 8-10 guy for years. Will quickly overtake people like Olsen, Walker, and Rudolph in dynasty value as he proves his quality and they keep getting older.
TE22 Tyler Eifert - He's a great talent. One of the best in the game. It's really just a question of whether his body will hold up. So far it hasn't.
OTHERS - I wouldn't break the bank for Jonnu Smith (TE25) or Gerald Everett (TE24), but they were high picks with intriguing athletic tools who showed glimmers of potential as rookies.
