It's possible I missed one or two (though I don't think so), but here are all the Duke players I could find in the Coach K era who in their first 12 games of the season averaged 4+ apg and 2:1 a/to or better:
SELECTED DUKE PG A/TO RATIOS AFTER 12 GAMES
Code:
Year Player 12gmA 12gmTO 12 a/to season a/to
2010 Jon Scheyer 77 14 5.50 2.98
2019 Tre Jones 67 13 5.15 ???
2018 Trevon Duval 80 23 3.48 2.03
1989 Quin Snyder 88 26 3.38 2.17
1997 Wojo 77 23 3.35 3.03
1986 Tom Amaker 82 26 3.15 2.51
2015 Tyus Jones 66 22 3.00 2.86
2014 Quinn Cook 78 26 3.00 2.68
2018 Grayson Allen 53 19 2.79 2.18
2003 Chris Duhon 98 36 2.72 2.16
1992 Bob Hurley 97 36 2.69 2.17
2001 Chris Duhon 63 24 2.63 2.85
1999 Will Avery 80 31 2.58 1.92
2004 Chris Duhon 76 30 2.53 2.16
1985 Tom Amaker 80 32 2.50 2.88
2002 Chris Duhon 76 31 2.45 2.26
1993 Bob Hurley 98 41 2.39 2.43
2013 Quinn Cook 71 30 2.37 2.41
1998 Wojo 64 28 2.29 2.56
This table tells me two things: (1) Tre Jones is having a great season so far (2nd best a/to ratio over first 12 games); and (b) it seems unlikely Tre's a/to will be above 3.0 by the end of the season.
Obviously only time will tell.
