How about...if we'd outscored them in the first half, quite possibly we would have had more than a 1 point lead with 4 seconds left, and a cushion even if a stupid foul was committed. Or maybe the cushion would have allowed more subs so the players on the floor weren't so tired at the end. Or maybe the timeouts could have been used differently so we would have had one left at the end. There are lots of reasons why that lousy first half affected the way the second half played out.
dilly(rhymes with silly)
of course it was the last 4 seconds, that is when the lead was lost, ergo "determined". Anything prior to that is history.
The fact that a game is 40 minutes long is immaterial.
If I shot you in the head, lol, and killed you dead would the fact that I shot 5 times before and missed you completely mean a damn thing in the end?
Why play the first half if it has no bearing on whether a team wins or loses?
