For Anthony Davis and Team USA, it’s all been building to this. A handful of exhibitions before the Olympics, five games of preliminaries and a knockout win over Australia were all played with the goal in mind of reaching this point: the medal round.At 4 p.m. ET on the NBC Sports Network, the Americans will take on Argentina in the semifinals of the Olympic basketball tournament for a right to play for the gold medal. Argentina, the lone team to knock off Team USA more than once in Olympic play since NBA players have been allowed to play in 1992, is perceived as the biggest threat to the Americans’ march to the gold.Team USA defeated Argentina 126-97 in the final game of preliminary play, with Davis tallying two points and two rebounds in 7:32 of playing time. Don’t let that lopsided score fool you though. The Argentinians will be ready to play. Five veterans from the 2004 gold medalists are on the 2012 roster, including San Antonio Spurs star Manu Ginobili.All that’s to say Team USA could be in for a test on Friday, meaning there’s a pretty good chance Davis – the squad’s 12th man – might not see too much playing time. Even so, it’s been an incredible experience for the national player of the year, who is over three years younger than James Harden, the next youngest player on the roster.Davis has played in five of the Americans’ six games, averaging 5.2 points, 3.4 rebounds in 9:33. He’s also shot 64.7percent from the field, not so different from the 62.3 percent he shot during his season at Kentucky.Anyway, tune into NBC Sports Network or watch the live stream here on NBCOlympics.com.
