IMO some of you are mentioning players whose value is already quite high and frankly FA has a better chance of lowering it. Ekeler being a prime example. He's going late 2/early round 3 of redrafts. Drake going round 3. I'm not sure even if Drake gets resigned and Chargers let Gordon walk we see those values increase? Maybe I'm wrong but would not increase to me. Gordon is also round 3 but I could see him improving a little since he's a year removed from being a first round player. I know this more of a dynasty discussion, or at least I think, but can draw some parallels from redraft value.
I'll mention some players I think can increase their stock and some of them can also decrease and I'll mention that as well.
Ebron, especially in TE premium leagues.
Chase Edmonds if they don't resign Drake. They would probably acquire a RB but he'd at least have a nice sell high window, like what we saw with Cohen last year from the timeframe of when they traded Howard to drafting Montgomery. Also I think Edmonds is just as good as Drake.
TY Hilton if Colts bring in veteran QB upgrade. He's being priced right now like Jacoby is his QB for life.
Hunter Henry and I say that because I'm a big HH truther but I'm worried about Tyrod/rookie QB duo and have lowered his current outlook because I don't think LAC will let him leave, they'll tag him if they can't agree on a deal. So if LAC don't get a vet QB and keep him, his stock is going down.
Amari Cooper and granted he could fall in value as well but I think there are a lot of places he could go and do a lot better then 119 targets which is awfully low for a teams #1WR. On that same note, if he leaves for some Gallup will increase. (Side note I think Dallas 100% keeps him if no new CBA is agreed upon before new league year but will get dicey if not)
Austin Hooper- I think he can drop a great deal. He and Ryan were good buddies, had a connection, had almost all of his production when team was trailing and teams were more willing to not let Julio or Ridley beat them.
Kareem Hunt could see massive increase if he gets out of Cleveland and becomes feature back, which I don't think he will.
On another note I don't think Steeler's sign a FA RB of note, some have put Gordon on Steelers, I don't see it but would be obvious blow to Conner.
I'll list AB because he's basically free and I still think he has a good shot to play next year but I'm not sure he should be in this discussion mainly because I think if he does sign with someone it's going to be more in the summer when his legal and NFL situations are possibly resolved. After all he's free to sign with anyone today, the FA period is not holding him back.
If Tampa moves on from Winston any QB that takes his job would see immense value increase.
Winston on the flip side of that can see his value crushed to the point of almost nothing.
Breshad Perriman, might be fools gold to me and you, but if he lands well his value will increase.
Robbie Anderson. Never been a big fan but he does separate well and starting to get hard to ignore the success of players who leave Gase. Put him or Perriman in Philly for example and I'm higher on them.
These two players are not FA's but when new league year opens so often does trade market. Njoku and OJ Howard could both strongly benefit from a change of scenery. I'd put Mike Williams in this group as well. I don't think LAC is inclined to shop him but he was criminally underused and if they feel need to move up for a QB they might have to part with something.
Emmanuel Sanders. I know he's old but don't forget how strong he started last year in Denver, it's extremely difficult to switch teams midseason at WR. Dynasty his value can't go up to much but could be a nice addition to get a team over the hump for a year.
