Same frailty score. Different edge, depending on your game.
Two RBs project for identical PPR at the same salary. One has a frailty of 82. Cash games are won by avoiding donuts — INJSUR makes that call quantitative.
A workhorse RB sits at 84.5 rushing yards. His frailty is 78. Even a mid-game tweak caps his snaps and tanks the over. Lean unders on high-frailty backs before the market reprices.
Two WR1s come off the board in round 2. One at frailty 35, the other at 71. Over 17 games, the high-frailty pick is materially more likely to miss 3+ games. Use the score to break ties.
Best ball removes weekly lineup decisions — only injuries sink you. A WR at frailty 27 fills your optimal lineup all 17 weeks. A WR at 68 at the same ADP leaves dead roster spots that no bench depth can fix. Draft the guys who stay on the field.
A RB at +1400 for Most Rushing Yards is priced assuming 17 games of volume. At frailty 83 his implied probability is far lower than the line suggests. The sportsbook can't price durability risk — but you can. Fade the fragile on season-long markets.
Dynasty managers need multi-year projections. A second-year RB at frailty 78 may flash for one more productive season; a rookie at 32 projects for a 5+ year prime. Use the frailty score to time buy-low windows and sell-high exits before the market catches up.
In auction drafts, every dollar spent on a high-frailty player is a double loss — the cap hit and the missed production when he goes down. Target low-frailty values in the $15–40 range where injury risk separates otherwise equivalent bids.
