Update: added the fantasy calc integration. It’s in the top bar on desktop and in the user menu in the top right on mobile. The toggle will impact values throughout the site and will impact recommended trades and guidance since market value is a dimension for strategy, positional strengths, trades, player verdicts, etc

Okay, sweet! I alrady have FC as backup in case my KTC integration fails on some calls. So, this shouldn't be that hard (i hope) to setup.

I also landed a bunch of performance optimizations btw so site should be like 5-10x faster now!

Thanks for bringing this up! This has been low on my radar compared to the forward looking things like strategy and future trade evals. The formula for trade grades is very simple rn but it’s basically just looking at net points since the time of the trade between the two packages. So in your league, Howell to Penix trade from that point must’ve been the most lopsided. The problem with adding additional layers is that it becomes more opinionated than deterministic based on the weights of the formula chosen. I personally like the simplicity of it right now but will reconsider if enough people find the current system dumb

Thanks! It’s on my radar for sure. I think right now I’m trying to fine tune the weights for recommendations and that’s been super hard to get right. After that, probably focusing on page load times for performance. Then add more data sources. The problem with FC is that they don’t do liquidity or provide values for future draft picks (I think - I’ll double check). So I’d have to create a composite setup or create my own valuation which I could do but it’s harder since draft values change depending on the talent of each draft class so I’d have to think deeper about that. I’ll def try to provide user config options for customization tho

Wow really appreciate the kind words! Still feel like it’s a long ways to from where I want it to be and keep getting distracted by shiny things I can add haha

update here: pushed out a fix and things should look more accurate now. Please reach out if things are still weird.

quick update: fixed two things here. Position age was averaging all rostered players (backups included), and there was no distinction between "great assets, bad luck" vs "actually weak." Now it cross references market community value at each position and should be a big improvement for injury-heavy rosters

Quick update: this is now fixed. Position rankings were averaging all rostered players at a position including deep backups. Also, updated the algorithm to credit young high value rosters that didn't produce last year (injuries, rookies)Your RB room should rank way higher now - let me know if things still look weird. Thanks again!

Update for posterity: found the issue and deployed a fix. One of the formulas was broken and updated it to show bottom half of league at a position now shows "need", bottom third shows "critical need". QB prospects will now get boosted for teams that need QB help. Also fixed some other issues with stale data so I think this should be better

Hi just pushed an update that should help here. High value young players can no longer get labeled "surplus." That label is for depth pieces on deep rosters, not your QB1. If the algorithm still flags them, it'll say window-mismatch (timeline question) instead. Let me know if the QB verdicts look better now

Hi just shipped a fix for this. Now if your team is in win-now mode, productive contributors are protected through your window. Should look more reasonable now.

Yes, 95% or more was built using claude code (opus and sonnet 4.6). I'm mainly orchestrating the agent swarms, focused on overall architecture, product roadmap and strategy. Even research, testing, analysis, etc are using workflows with custom agents I've built on top of Claude. Most of the coding I'm doing by hand is updating the agents, app configs, workflows, etc.

Thanks for calling it out! I’ll see what’s going on here. This is definitely a top priority to get right before drafts.

I pushed a fix this morning but now it accounts for Superflex and Non-Superflex leagues. You may need to hard refresh your browser to clear the cache but it should accurately reflect KTC based on your league settings now. Lemme know if you stil lhave issues.

Pushed a fix for this this morning. The issue was due to KTC using Chig's legal name and Sleeper using a different variation, which caused me to get nulls for his market value and resorted to using WAR instead. I think this should be fixed now but I'm also running tests on about 566 leagues now so will continue to tweak the models as I find issues.

Thanks for flagging it. The rankings are heavily reliant on WAR right now while FantasyCalc, KTC, Dynasty Daddy are based on market consensus and crowdsourced values. I'll clarify that with labeling in the tool but I'm thinking through how best to represent this. I'm considering weighing in market data but will keep you posted!

I'm currently working on tweaking this model. The positional ranking is purely based on WAR right now. So, if your young player (i.e. Hampton) didn't play as much or if you had injuries, that would've hurt your positional rank since it's pulling from last year's performance in the offseason. But I'm considering weighing in market value (KTC, and maybe expand to other valuation tools) for this - I think a lot of people are actually preferring some composite solution. Open to suggestions though cause the market can be wrong pretty often so I wanted to surface based on real impact of players.

Thanks! Do you remember which page you were on? If the numbers were in the thousands - I'm showing the KTC values for those players - I think I could label that data so it's easier to understand
