1) Does that include the Special Teams players?
2) Is that not a bit extreme? I tried it and it felt like now even trying to invest in players, no one progresses anymore. Even then I only knocked each slider down 5 points. It's a small sample size so far but it feels strange that even Star development players make very slow progress, even if it has the intended effect of Normal development players not really being able to be much better than they currently are.
Thinking about it, I'm kinda back and forth on it, but I'd think I'd lean faster rather than slower, simply because football moves pretty damn fast and in a lot of cases, when a guy "has it", they show it right away. Josh Allen is kind of one of the few slow developing guys that took a few years at QB, and many young skill position players break out right away. Certainly there's still a curve to it, but generally if they're good right away (in the case of Madden, inherently had a better development trait), I not only don't mind but expect those players to quickly reach 80+ OVR and beyond. Even then, it's not like it happens within one season. A low-70s Star player fresh from the Draft usually needs about a year and a half to get to 80. And maybe those really highly rated draft prospects with Star or better get close to or past 80 their rookie year before then completely exploding upward once their Dev Trait is no longer Hidden.
On the other hand, I know you had balance in mind in terms of equalizing the talent over the long term, especially for the player who gets many bonuses, so it's a tough balance. I'd like to think Star or higher players *should* progress quite quickly but if it means the guys who fall lower on the depth chart, from veterans to newer draft picks, never get to see the field when they would normally, I could see how that can create a new kind of stagnation.
I did use your set from last year for last year's game, and I think it was pretty good, if maybe a tad fast: I remember my freshly drafted Star players (in the low 70s) gained perhaps about 6-7 OVR rating points over the course of a year, and turned a late-round 67-ish Normal development backup linebacker into a 74 OVR by the end of his rookie contract. Also, a drafted Normal development WR I used immediately as a starter raised by about 5-6 in a full year starting (before then earning Star development thanks to winning ROTY). Is that the development curve you expect or is that too fast? Because at the time, I didn't use Progressive Fatigue then, either, and it felt fine, if not maybe a tad too fast in terms of game balance, since my QB developed quickly lol. Even then, part of that might've come down to other sliders I used that may have made the game too easy for me thus being able to feed his stats more easily. Maybe part of why it felt so glacial this year was that I found a better gameplay slider set that made the game more challenging for me and therefore gives me less opportunities to pad my player's stats.
Like I mentioned, I've been back and forth between keeping it as is and reducing it all by 5-ish as per your recommendation, but I wanted to have a better understanding about your philosophy with your Slider Set to have a better idea of how to tune it for myself.
EDIT: I think spending this time typing out and estimating the OVR rating points my young players gained over the course of a season, especially as starters, did end up convincing me that I should probably bring those sliders down, though still unsure by how much (I still feel like I wanna try -5 first, 10 or more still feels a bit extreme to me). Still hesitant, but now thinking about it, it does make for a more interesting development cycle, because it really would emphasize the playtime even more. Anyone relegated to backup, even if they're someone I wanted to try to make into a future starter, would struggle to develop unless I actually put them on the field, even if I focus my efforts with Coach Perks and Focus Training into them, which is a fun consideration to have to make: put out the underdeveloped young player or the low-potential veteran who can already play.
