This is absurd. Tony Parker for a long stretch of time 2 seasons ago had a top 3 FG% in the LEAGUE. Not for point guards. For anyone. That kind of scoring efficiency at ~20 points per game is absolutely unheard of from a point guard. In fact, only two other players who ever played the guard position reached 18+ PPG and managed to score at a rate of 54.8%+ from the floor: Magic Johnson and Walter Davis. Both of them were considered guard-forwards. Davis didn't play the point, so he can effectively be eliminated from this comparison. Source:

That leaves two. Two players. Magic and Tony. And Magic could easily use his post-up game to score at will against smaller opponents, allowing him to even play the 5 at some points in his career.
No one from a pure point guard style of play has ever done what Tony has managed in his career. In fact, only two players in NBA history have ever managed 5 seasons of 17+ points per game while shooting over 50% from the field: Tony Parker is one of those two players. Source:

But yeah. He was just lucky that everyone else was dimming, because he was really just a "good" PG who got put in the right system, right?
