General Manager / D-League Draft / Defensive Strategies

If I deselect the "Use coach strategies", does that mean I control everything? What will the head coach offer me then? In other words, am I better off getting a cheap head coach if I am going to control everything?
Where do I set defensive strategies?
Also, for some reason, I can't select players in the D-League draft. I could in the demo, but in the full version, it is greyed out.
By the way, I see there is no manual. Where do I get the information I need besides going through the threads here and asking a thousand questions?
Anyone recommend a webpage for a new coach? For example, explaining spot up offence.
Thanks
