Three other ways to ask

Each answers a different question, so none of them replaces the replay above.

The closing betting line, turned into a probability. What everyone knew before the game.

The line plus what this game showed, weighted by how much one game can tell. It stays close to the line because one game says little.

Every kick, fumble bounce, drop, conversion and judgment call redrawn; everything else fixed. The narrowest view of luck.

How 4,000 replays ended

Panthers win 24% of them, Buccaneers 76%, counting the 2% still level after regulation as half each. The line is what actually happened: Buccaneers by 14.

  • R. Succop, 33 yds made · 91% expected
  • J. Slye, 23 yds made · 98% expected
Bar: expected chance of a make. Filled dot: made. Open dot: missed or blocked.

  • Dennis Daley (CAR G), out · 0.3 pts
