That team avged 87 ppg and only took 245 attempts behind the arc all year. Only 2 players attempted more than 33 for the season. You can still score lots of points even if you don't take any 3 pters. There didn't used to be a 3 pt line and nobody really guarded out to that distance, and teams still scored just fine.
