If I were estimating/projecting right now, I'd say:
Arizona=1. Drake 2. Edmonds, I'm not a huge Drake fan but I think he'll likely be brought back unless he wants like 8+ a year.
Atlanta=1.? 2. Smith, I think Atlanta likes Ito Smith as a backup, and some combo of Hill/Ollison fill out a position, but #1 is up for grabs. I think this is a very interesting spot for 1 of their 2 2nd round picks. Maybe local star D'Andre Swift?
Baltimore=1. Ingram, 2. Hill 3. Edwards, they are set
Buffalo=1. Singletary 2. ?, I think they replace Gore with a different, more versatile veteran. Devonta Freeman makes sense to me.
Carolina=1 CMC 2.?, I imagine the Panthers add a day 3 pick to Bonnafon, Scarlett, and co. Ke'Shawn Vaughn feels like a nice pick for them.
Chicago=1. Montgomery 2. Cohen, I think they just roll with that, and hope for a breakout 2nd year from Montgomery.
Cincinnati=1. Mixon 2. ?, I really think Bernard gets cut, and he should, he's no longer an effective RB, and is highly paid. I think a they add a day 3 pick to the Williams/Anderson picks from a year ago. Cam Akers at the top of round 4 gives them a high upside alternative should Mixon want the big bucks he's rumored to want, and be a solid #2 in the meantime.
Cleveland=1. Chubb 2. Hunt, I think Hunt gets tendered at a 2nd round level(at least) and just don't see anyone ponying up a 2(or more) for a RB who was suspended for half a year.
Dallas=1. Zeke 2. Pollard, Pollard looked more than good enough to not face any competition for the #2 job.
Denver=1.Lindsay 2. Freeman, this combo is likely going to play out their respective rookie deals together. Cheap, solid, and complimentary.
Detroit=1. Kerryon 2.?, I think they can't feel good about Johnson's durability, and nobody really impressed in his absence. A veteran like Lamar Miller would give them a nice alternative, who could at least be a solid fill-in should Johnson's injury woes continue.
Green Bay=1. Jones 2. Williams, like Denver, they are riding out their rookie deals together.
Houston=1.? 2. Duke, I think at this point we have to accept Johnson will never be more than a 3rd down guy. Hyde only gets what is blocked. I think Houston takes a RB in either round 2 or round 4. I think they'll take JK Dobbins if he's still there at 57.
Indy=1. Mack 2. Hines, they seem to like Mack a lot more than I do. Sounds like he may get an extension soon.
Jacksonville=1. Fournette 2. Armstead, too many other holes to address RB. Hopefully they don't extend Fournette.
Kansas City=1.?, 2. Williams, Williams is a solid RB, but he's more of a RBBC guy than a true starter. Thompson didn't show a ton, and I think they wanted more from the position, Williams playoff run notwithstanding. I doubt they draft a guy on day 1, but day 2 is a possibility. Maybe Zack Moss?
Las Vegas=1. Jacobs 2.?, Richard re-signed, but I don't think he's getting the #2 job handed to him. I like Matt Breida here, SF soured on him as he dropped to 4th by the Super Bowl, but he's been a big play magnet, and offers much more than Richard as a runner.
LA Chargers=1. Ekeler 2. Jackson, I think they have no reason not to just roll with these 2. Both have been very good in smaller roles.
LA Rams=1. Gurley 2. Henderson, not buying Gurley as a cut at all. Maybe if Henderson had done anything as a rookie, but he didn't even beat out Brown yet.
Miami=1.? 2.?, I'm not confident their top-2 RB's are currently on the team. With the league's most cap space, and likely breaking in a young QB, I think Melvin Gordon makes a lot of sense for them. In addition I think Clyde Edwards-Helaire makes sense as the Ekeler to Gordon's, well, Gordon.
Minnesota=1. Cook 2. Mattison, pretty set there.
New England=1. White 2. Michel, don't see them adding a RB, more likely to just involve Harris in Burkhead's old role, if they don't just bring Burkhead back.
New Orleans=1.Kamara 2.Murray, pretty set there. Curious if they extend Kamara coming off a down year.
NY Giants=1. Barkley 2. ?, I'd like to think they wouldn't just roll with Gallman as the #2. Jordan Howard is a nice, likely cheap option, who can keep the chains moving, and perhaps also allow Barkley to split outside more often.
NY Jets=1. Bell 2. ?, I'd be shocked if Bell was gone, unless they Osweiler'd a deal to take his contract. Montgomery/Powell could be upgraded upon in the meantime. I think Jerick McKinnon would be a cheap worthwhile flier.
Philadelphia=1. Sanders 2. Scott, I think Scott showed enough to go into the year as the unquestioned #2.
Pittsburgh=1. Conner 2. Samuels, the Steelers have limited cap space, and draft capital. RB just needs better health, and they do have Snell as a #3.
San Fran=1. ? 2. Mostert, I think another RB is added, its just Shanahan's style. I think McKinnon is cut, and Breida is let go as a RFA. With no 2nd or 3rd round picks, I highly doubt the 49ers stay at 31, in the ensuing trade down(s) a guy like Jonathan Taylor may very well appeal to them.
Seattle=1. Carson 2. Penny, not seeing them investing any more at the position. Could see Homer being the #2 as Penny works back.
Tampa Bay=1. Jones 2.?, I still think Jones has a shot here. He'll get competition for sure, but I think it'll be someone to fill the pass catching role, and maybe 50% of Barber's carries. David Johnson seems like the natural fit.
Tennessee=1.Henry 2.?, Henry will either get a contract or tagged. Dion Lewis is likely where some of that money comes from. I think getting Henry more involved on passing downs will be a priority, so i don't think they automatically look for a 3rd down type. I think Carlos Hyde fits here, as he's around 30, and can "in theory" do some of the same things Henry does.
Washington=1. Guice 2.Love, I think Peterson is a nice veteran insurance policy, but ideally he's on the bench, and the young guys step up.
