The key numbers
NFL margins of victory cluster at 3 (field goal) and 7 (touchdown). About 15% of games end with a 3-point margin; ~9% end with a 7-point margin. These are the most common results — and the spreads cluster around them.
Buying off the 3
Moving from -3 to -2.5 (or +2.5 to +3) shifts you away from the most common result. The vig cost is 25-35 cents — among the most expensive moves in betting. Generally avoid.
Teasers through 3 and 7
The classic +EV play. A 6-point teaser moving -8.5 down to -2.5 (or +1.5 up to +7.5) crosses both key numbers. Historically, these teasers have been profitable for sharp bettors. The book has tightened pricing in recent years; verify on each individual teaser.
Sharp NFL strategy
Take early-week numbers. Shop player props aggressively. Skip boost traps. Track CLV — your closing-line value is the only honest signal of long-term profitability.
