It was the first win for new head coach Pierric Poupet, and it came because of ball movement and paint dominance.
ASVEL reigned inside in win over Crvena Zvezda

LDLC ASVEL Villeurbanne overcame a slow start to the game before its offense started clicking en route to a 100-91 triumph over the visiting Crvena Zvezda Meridianbet Belgrade on Tuesday night.
ASVEL finished the game with 21 assists, which is 3 more than Zvezda, while both teams had the same number of turnovers. It is only the fifth time this season that ASVEL had more assists than its opponent, and it has now won three of those games.
However, the main reason why ASVEL won is down to the job it did in the paint. ASVEL outrebounded Zvezda 38-26, including 14-9 on the offensive glass. That said, 3 of those Zvezda's offensive boards came in the final 2 minutes and 20 seconds, when ASVEL was already holding a 12-point lead and had the game all but wrapped up.
In addition, defensively, ASVEL held Zvezda to 22-of-34 two-point shooting. Zvezda made its first 7 two-point attempts, which helped it open a 9-point first-quarter lead, but after that it shot 15-of-27.
All of that combined led to a big win for an energized team and a debut win for a 39-year-old first-time head coach in Pierric Poupet.
