Despite going 5-0 in its exhibition run leading up to the Paris Olympics, the Team USA men's basketball team showed some flaws in close games against Germany and South Sudan.
Per ESPN's Brian Windhorst, head coach Steve Kerr was not happy with some of the things he saw during a film session and put the team through its most intense practice of the summer on Thursday in preparation for Sunday's Olympic opener against Serbia.
"That's what today is about. It's the reminder. It's time. We're here," Kerr said. "So it's got to be 40 minutes of force and attention and focus, and we can't let teams outplay us effort- and energy-wise like we did the other night against Germany, like we did against South Sudan.
