Allen Iverson hasn't been able to achieve such thing because of his low FG%, Shaq was closed in 99-00 hitting 956 & 29.7 ppg
You need these in order to make 1000 FG
- Attempt lots of shots
-High FG
-Endurance
And just for fun Wilt Chamberlain made 1597 from the field the season he averaged over 50 ppg

So who will be the next one to make 1000 FG?
