Bball Drills with just one or two people.?

I would like some drills I can do myself to enhance my bball skills, particulary speed and defense my two weakest points. My coach told me to jump rope everyday for speed, but what else can i do ? And I would still like to practice everything else to. I know a few drills, but im tryin to find enough drills so i can practice 3hrs. I play SG if that helps in some way. Thanks.
