What an upset does and doesn’t tell you
Four teams have won as 8.5-point underdogs, the biggest upsets of the 2026 NFL season so far.
Big underdogs lose far more often than they win, which is why these games stand out. An upset shows the spread was wrong once; it does not mean the same team will beat the number again. Check the current line, injuries, and the opponent first.
