His impact ain’t done yet. But one can argue that even if he retired tomorrow Steph would arguably be the greatest Warrior of all time.
Steph Curry is the greatest 3 point shooter in NBA history and has helped the Warriors go to 4 straight NBA finals, while winning 3 of them. Curry broke the all-time NBA 3 point record in a season, then went on to break his the next season again.
He helped the Warriors win an NBA record 73 games and won back to back MVP awards. He also became the first ever unanimous MVP in NBA history.
