Attribute Realism for Franchise and RTTS has been uploaded to the vault
-
Hi all,
The first iteration of Attribute Realism rosters has been posted to the vault. After it surged to great popularity last year, I figured I’d make this post and let people know that it is out again, as well as talk a bit about my process.
I’m a one-man team and I try to play favorites with teams and players as little as possible, letting the stats and math that players produce speak for themselves.
Every single player on every single roster has been edited to be more in-line with who they are as players in real life, including minor leaguers. This involves everything from changing minor league pitch mixes, to changing walk and strikeout rates across the board, to increasing steal rates and steal success, to changing contact rates and H/9s to account for an ~.240 league wide batting average. Unfortunately, you can’t just copy and paste savant pages into the game because attributes aren’t percentiles. They all have to weighed against the other stats that effect results while simming.
The goal of all of this is to produce the kinds of stats that players do in real life, and to that end, I’ve run 100 season long full simulations in franchise and RTTS to make sure that everything is as it should be.
Of course, it isn’t perfect; nothing can be. But, while other rosters often over-inflate the stats of their favorite teams and players, I’ve tried to avoid that as much as possible. The stat formula I’ve used also weighs outlier seasons less than SDS does, in order to cut through the randomness of small sample sizes. I.E., a 2024 season in which a player hit .150 against lefties in only 50 ABs should not weigh more than the three previous seasons in which they hit .300 against lefties in 450 total ABs. Baseball is random, and small sample sizes happen.
The biggest difficulty is AAA/AAAA players. The game has no real way to distinguish between players who dominate AAA and flail in the MLB—you end up with either overinflated stats to reflect minors success, or underinflated stats to reflect majors struggles. Attribute Realism splits the difference, so you won’t have career minor leaguers dominating in the majors, but you also won’t have guys who aren’t regulars at the MLB level, but are still good enough to be called up sometimes, aren’t rated 55 overalls (of which there were so, so many).
I've worried less about making sure that every 40 man roster is perfect, since those change frequently, and more about making sure that every prospect and every player that should be there is there, and that their attributes reflect their production as players.
The roster is also up-to-date with every roster move that has been made before 4/24/25. If I missed anything, please let me know, but it should be completely up-to-date.
Obviously, baseball is baseball and outliers will happen; but, the goal is to make it as close to reality as possible. It’s taken ~250 hours to do, and I hope you will all enjoy.
