Early concerns with Carter-Williams

Rookie point guard Michael Carter-Williams stuffed the stat sheet in his summer league debut on Sunday, finishing with 26 points, 7 rebounds, 8 assists and 9 turnovers for Philadelphia. For a player who didn't score a whole lot in his two seasons at Syracuse, the 26-point outburst had to be encouraging. But for someone who may have to start from day one with the 76ers, the turnover count was far too high.

So what's the biggest concern with Carter-Williams?
