savant

savant

see players from a new perspective…

you know your guy is better than their guy. now you can prove it with context-cognizant insights that separate the players from their surroundings.

whether it’s a qb threading a throw outside of structure, a back creating yards on his own, or an edge defender turning clean pockets into chaos—savant identifies skill that beats the play call.

if it translates on sunday, savant sees it.

example savant cluster cards comparing two players across attributes like fight, clear, runway, break, churn, snip, torch, window, and trust

delta

true team strength at a glimpse…

delta isn’t about what happened. it’s about what mattered. at ykb we track impact per snap—not raw totals without context. explosive plays against elite defenses weigh more than empty yards in garbage time. opponent-aware insights reveal where teams and units really rank.

delta sees through volume and cuts straight to value. efficiency and explosiveness weighted by the opposing unit. delta rewards the moments that mattered—drives that flipped momentum, stops against real offenses, gains against real fronts. no fluff, no inflation. just opponent-adjusted insights that reveal true team strength.

example delta cards comparing three teams: seattle seahawks running hot at 8.44, pittsburgh steelers in the middle at 5.05, and new york jets running cold at 1.70

cadence

your own football analyst, on call…

meet cadence. ask it anything, in plain english: who led the league in explosive runs. how a rookie’s targets changed after the bye. mahomes vs allen by epa per dropback since 2022. cadence answers with a live query against real nfl data, not a hot take.

every answer shows its work: the query, the numbers, the chart. save the good ones to your own library and build the case for your guy. no vibes, no narratives. just receipts.
