i believe also that those skill exist, my long time for example is one of them. He also made nearly no turnovers, in the beginning of the career with the weekest skillset of a guard later on i got 2 pretty similiar one and he beats the other player easily in this category too.
This is the guy ->
(3165648)Season four: 15,1 As/To - Ratio
Season 5: 49 As/To
Season 6: 11,66 As/TO
Season 7: ~4,8 As/TO :(
Season 8: 11,5 As/To
Season 9: 7,875 As/TO
Season 10: ~6 As/TO
Season 11 till now: 7,25 As/TO
Even in his weakest season, i beleive he was best guard depending on AS/TO, weird thing is that this was probadly the season where he was "outstanding" a bit in league today he is more below average depending on Skill for a Starting guard in my league, with handlin 11 and passing 13.
I don't have a bigger sample, but this guy always make me believe on maybe a hidden security skill.
