Marquis Teague did all he was expected to do Wednesday. He learned. After a rough debut Tuesday night in the Bulls’ NBA summer league opener in Las Vegas, Teague looked a little more like a first-round draft pick Wednesday afternoon. The 19-year-old rookie from Kentucky scored 14 points on 6-of-13 shooting, with five assists, five turnovers, one steal and one blocked shot in the Bull’s 96-88 loss to the Houston Rockets. ”I just knew what to expect when I came out,” said Teague, who scored eight points on 4-of-17 shooting with one assist and six turnovers against the Celtics on Tuesday night.
