Had the same issue and it’s incredibly annoying and takes away from the Dynasty playing experience.
I‘ve tried multiple runs with different coaches with the Roster Retention Tiers in the Program Builder section locked or unlocked and there is absolutely no difference.
What I have observed is that you can influence Transfer Portal behavior and the chance to successfully persuade a player either via the „User Player Transfer Chance“ slider or the overall skill level. If you adjust the latter to „Freshman“ once you’ve hit the week when players leave, the chance to successfully persuade a player rises significantly. That however has zero impact on those who declare for the Pro Draft.
For those declaring, and the likelihood of a successful persuasion I see two metrics, one is the overall rating of the player, the other are individual trophies/accolades that player has won. If for example you have a 90/91 rated player that would be drafted in rounds 5-7, and that player has been named to an All-American team, the persuasion chance is „None“.
In my opinion it’s just super frustrating. I crawled different forums and while I understand the „just let them leave & recruit new players, it adds realism“-fraction, I tend to play dynasty mode differently.
There is only a limited number of NIL-licensed players, and given that recruiting classes are (understandably) randomized, naturally you have less „real“ players each year. Normally I play a dynasty for 2-3 seasons and then start over again, sometimes with different teams, challenges etc.
For that reason it’s incredibly annoying when in addition to the outgoing seniors, a large amount of underclassmen declares for the draft early without a real chance of persuasion. And I’m not talking about a Junior player who has started for multiple seasons and is expected to be drafted in the first round. But more about the Sophomores (RS), the players with max. 1 year of starting experience, particularly when they would be drafted somewhere between round 4 and 7, who could still gain from staying for another season, continuing their development and increasing their draft stock to be a 1-2 rounder.
For example, I had a dynasty with Texas, winning the title in year one. After the season Arch Manning declared for the pro draft, he was a 2nd or 3rd team All-American, was projected to go in round 6 and the persuasion chance was „none“. I went back to an earlier save point, simulated without Arch winning All-American honors, he still declared for the draft as an expected 6th round pick, only the persuasion chance was „Extremely Low“ or „Very Low“. Either way that’s just an incredibly unrealistic outcome, having a RS Sophomore declare early to be drafted in +/- round 6.
In the same dynasty I used the 100 preorder bonus points to unlock the three tiers in „Roster Retention“ for Steve Sarkisian … after the third year (partly simulated), I am still waiting for my first successful persuasion of a player intending to leave for the NFL.
All in all a very frustrating experience that takes away far too many NIL-players early. At least make it manageable … those who want that element of realism can use it, but provide a slider or make the difficulty settings apply for those declaring for the Pro Draft, … for those who’d like to keep a couple of licensed players along.
I wish EA would do something about it, but given the issue I’m not getting my hopes up. Frustrating.
