The closing line is the final price available immediately before an event starts, and it's generally regarded as the sharpest, most information-complete number in the entire betting window - see CLV above for why that matters. Everything that's going to affect a game's outcome that becomes public before kickoff - injury reports, weather, lineup news, sharp and public betting volume - has, in theory, already been absorbed into the closing number.
