SJ, Spain is doing the same in their warm-up games, just saying. Russia, Argentina and Lithuania. By 20 all of them (ok, the 1st time against Argentina was by 2, because Spaniards lost intensity at the second half).
Ultimately it is a 2 team race between Spain and the United States. I think the Americans get an advantage by getting to play Spain in the Round Robin part of the tournament. So they can use film from that game and break it down. That could be an advantage for them if they do a good job with that info.
Spaniards can do the same, so the advantaje will be for the team whose coach and assistants are better. But it will only be true if the difference of quality between both teams isn't too big IMO.
