I've been playing dynasty fantasy football for over a decade, mostly on Sleeper, mostly in 12-team superflex leagues that are at least three years old and at least one rebuild deep. SharperSunday is the tool I wanted and couldn't find — an AI co-manager that actually knows my roster, my league's scoring, and where I am in my win window.
Every post on this site is human-edited. I don't get paid to recommend players. You can try SharperSunday free at /signup — it reads your league in about a minute.
Edge is priced from trades, not opinions — see how it's built.
