I'm not sure this is entirely fair.
Grayson shared the ball about as well as any player outside the PG position.
I looked at assists per game stats (not an absolute measure of "sharing the rock" but as good of one as we have that doesn't involve bias) for the ACC last year, and there were only 13 players in the conference with more APG than Grayson (and only one of those outscored him). Of those, nearly all were PGs. Those who weren't PGs: Miller-McIntyre (SF), Gbinije (PF), Jackson (SG/PG year before last), and Paige (SG). I got positions from the link below, so you may argue some of these, but I think the point stands.
Not my intention to blow up the thread - but I don't think the quote above is accurate.
FWIW, Wake and UNC were the only 2 teams with 2 players who had more APG than Grayson.
