We can definitely afford to wait for the right point guard. Branch is top-notch, and Greene and Harrison will only get better.
I'm very impressed with Harrison's handle and vision. I think we'll see more of him with the ball in his hands as other step up their scoring. The kid is going to be unguardable running pick and rolls as his game advaces.
Samuels isn't the answer. But Branch is still largely unknown( hes played 10 games in college, none better than 6pts and 6 assists) and aside from height, Harrison's biggest weakness is his lack of court vision. Far from being a strength, he needs to learn to pass out those pick and rolls. Last year he was incapabable of finding his pick man after he turned the corner he just put his head down.
Ball movement held us back as much as anything. Hopefully Branch can help change that. But I wouldn't say we can afford anything at this point.
