I would rather Colvin and DG both start rather than one or the other. DG is our best penetration option in the half court besides Gilstrap. I would like to see what he can do cutting off screens and moving without the ball to get looks. When you talk about managing games what other stat would you look at besides A/T for a PG? Hes not shooting too badly, he is at 44%. He's also shooting 40% from 3. He also handles the ball better than anyone on the team.
How many assists of his come after he dribbles around for 20 to 25 seconds and then throws a pass for someone to take a desperation three? If they make it he gets an assist and if they miss no turnover. When does he ever make a clutch shot? Most his points come when the game is already decided, ie. today.
Colvin is by far the best penetration option we have. He does make mistakes but they are usually aggressive mistakes. He needs time to continue to develope. Give him three years of starting experience and he will be leaps and bounds a head of where DG is today.
