Look: you’re tossing units like confetti, hoping something sticks. The problem? No structure. No plan. Just raw guesswork that leaves you flat-lined by halftime.
Here is the deal: a unit is a slice of your bankroll, not a fancy term for “I feel lucky.” Most pros lock it at 1-2% of total funds, period. Anything else is reckless gambling, not strategic betting.
And here is why you can’t treat a quarterback rushing yards prop the same as a player-to-score-twice bet. The variance on a 50/50 prop is low; the variance on a 10% long-shot is sky-high. Adjust the unit size accordingly — shrink for high-variance, stay steady for low-variance.
Think over/under totals, over-under receiving yards. You can afford 1.5-unit bets because the outcome swings are modest. Your edge is thin, but the bankroll erosion is slower.
Think player-to-score-multiple-touchdowns, any-time touchdown scorer, or odds-boosted props. These are lottery tickets. Stick to .5-unit stakes or even less. One miss won’t ruin you.
Flat staking is king. Bet the same unit every time for a given prop category. It eliminates emotional tilt and keeps variance predictable. Progressive methods — like the Kelly criterion — are tempting, but they demand precise edge calculations you rarely have.
Take the upcoming Patriots vs. Steelers game. The over/under on total passing yards sits at 265.5. Your edge? You’ve crunched the data, you see a 55% chance it’ll go over. That’s a thin edge, so you place a single unit.
Now, the “anytime touchdown scorer” prop for the rookie running back is a 12% probability. That’s high variance. You allocate .5 unit. You’re protecting the bankroll while still chasing the upside.
Never chase losses with bigger units. That’s a recipe for a busted bankroll faster than a fumble. If you’re down three units, stay the course. Reduce the stake, don’t double it.
Use spreadsheets to track unit performance, not just win/loss totals. Plot your equity curve; if it’s jagged like a roller coaster, you’re probably mis-sizing. Adjust until the curve smooths out.
Stop guessing. Adopt a disciplined unit size — 1-2% flat for low-variance, .5-unit for high-variance. Keep your bankroll breathing. unit sizing NFL props is the only way to survive the season. Start applying this now.
