actually 4 assist a game isnt bad already,
if your basing stats by means of average he should get then we have somewhat mis-understanding. because even if you have a bloody hell steve nash like passer but your team offensive skills aint up to the level wherein it needed to be in a game youll struggle.
dont event think he should be having 8 or 10 or 12 assst even with proficient or prolific.
in the nba, there are only a number of pgs who can average double digits in assist namely nash, baron davis, etc and some can but doesnt go on regular basis like jason kidd, jason williams look at him when his memphis and to miami
aside from the basics of strategy we must also see the players itself running the plays.
also for a nba stand point a pg who averages 6 assist per game is already consider above normal, especially on a fantasy stand point of view.
