We'll get to the Gasols later. Right now, let's talk about Spain's defensive ace: Oklahoma City forward Serge Ibaka.
Tyson Chandler doesn't play offense. Anthony Davis is pretty deficient in that area as well. Kevin Love is a scorer, but he'll likely spend a decent amount of time on the perimeter stretching the floor.
In other words, Team USA's big men aren't going to do much scoring. Serge Ibaka should be able to severely limit whatever scoring they were planning on doing.
That also means that nobody is going to get Ibaka into foul trouble. He'll be able to defend the rim on drives by LeBron James and Kevin Durant without worrying. This will make a huge difference in keeping the Americans away from the hoop.
Spain simply can't keep up with Team USA in a track meet. They're too fast, too small and, overall, too good. Ibaka's defense is going to have to keep Spain in the game.
By the way, Ibaka was excellent on offense early in their exhibition matchup last week. If he can score, Team USA will be in serious trouble.
