Actually 3 pointers are more common and higher % than ever in recent years if I remember correctly.
Bill Laimbeer, a C, shot 33% from 3 for his career (same average as Jordan). Bird SF/PF had a 38% average for his career. Ainge closed at 38%, Byron Scott at 37%, Chris Mullin 38%, Mark Price >40%, Dale Ellis at >40%, Hornacek >40%, Steve Kerr >45%, Glen Rice 40%, Reggie Miller nearly 40%. More recently Nash will close at around 43% and Ray Allen at 40%.
As you can see claiming that Jordan's era was 'different' doesn't mean that Jordan was certainly not a great 3pt shooter compared to his peers. He was decent, just not great. In today's NBA he wouldn't be Josh Smith-level terrible, but pretty terrible anyways.
