I watched some of those Team USA games and the team was not very good, Joe Jackson was out of control, Patric Young can ONLY dunk, rest of team terrible, and Lamb was clearly the best player / their only chance of winning games against the better squads...
I usually really like Winn's analytical articles (defense in title game is obviously my favorite), at least he is providing substance and not just rambling opinion like most "experts."
But in the context of a team comprised of a group of players that get to practice together only ten times or thereabouts before playing an international tournament, stats like usage rate really aren't as telling...
Watch the Lamb highlights from the Lithuania game and that is the best thing to take away from it...
