It is obvious that Frank does not run many plays for the guards, I think he expects them to get their shots in transition and off of the passing game. So whoever is playing the two spot is probably nightly not going to get deep into the offense without creating it for themselves.
However it still does not take away the fact that he doesn't confidently step into a shot when he gets the ball from either the mid range or perimeter.
I like Lance, he had a couple of shaky games but that is to be expected. Also I've said before that I think Lance best position is point guard because he has the handles and the passing to play there and because he doesn't have the ability to excell at playing off of the ball.
But that is just my opinion on the matter.
