Ben Simmons had a monster night in Dallas Saturday — 23 points on 15 shots, plus eight assists and seven rebounds. The Mavericks’ defenders simply could not stay in front of him, and Simmons was 9-of-12 shooting in the paint on the night. Needless to say, the rookie impressed Dallas coach Rick Carlisle. Simmons has impressed a lot of people this season, averaging 17.5 points, 7.5 assists, and 7.3 rebounds a game through six games this season.
