It is going to be a pretty easy decision by the time the end of the season rolls around.
If he can pick up his FG% and keep playing solid, improving slowly, 4 million for a good tall PG will be a bargain.
If he is so so, then we don't pick up his option and just offer him less.
Consider, in 3 games the guy is averaging 12.3pts 3ast 4rebs 1stl in 20mpg. 10-26 fg 3-8 3pt in limited minutes (taken from the other board.)
I don't think it is a stretch that he can improve some.
