U.S. men’s basketball wins big over Iran
The U.S. men's basketball team's 120-66 win over Iran on Wednesday felt like a throwback performance by a team and country accustomed to global domination and lopsided Olympic victories.
It came on the heels of the team's stunning opening loss to France on Sunday, the United States' first since 2004. For the U.S., which also dropped two consecutive games in exhibition play, the loss raised concerns and placed unanticipated importance on the team's matchup against Iran. And the Dream Team, or Redeem Team, or In-Need-Of-Some-Self-Esteem Team, or whatever the 2020 Tokyo Olympics squad eventually will be nicknamed, responded with a dominant performance.
The shooting woes that hampered the U.S. against France were non-existent against Iran, as Team USA shot 55.3 percent from the field and hit 19 3-pointers. Damian Lillard went 7-for-13 from 3 to lead the United States with 21 points.
