About Next Man Up

Most lineup tools hand you one number and expect you to trust it. Next Man Up does the opposite: every player shows a floor, a projection and a ceiling, how far that projection sits from their own season average, and how much confidence the sample behind it deserves.

The name comes from the oldest truth in football. Snaps, carries and targets do not disappear when someone goes down — they move to whoever is next. Pricing is slow to follow, and that gap is where value lives.

The builder runs entirely in your browser. Your salary file never leaves your machine, there is no account required to use the optimizer, and the math behind every column is spelled out on the projections page.
