USA ed around too much in this game. They just had to find out if they could flip the switch when it got close so there would be no question about if they could win a close one...everybody already knew they could dominate, so not much would have been gained by them doing so.
They wanted it close to prove they could do it, at any point they wanted, they wanted Spain to have a chance to take it, to give them a reason to fight their hardest at the end.
Made for a better finish but the cloeseness of this game was artificially created by the players...
Example:
I could have gone outside and took a piss while that one guy was allowed to spot up for a 3 . Then they did it again on the same posession...
