I like to do basketball shooting drills for cardio sometimes, but I NEVER play vs others (too easy to get injured, bodybuilders have no business playing basketball). The trick is to wear a heart rate monitor and keep adjusting the pace (without stopping) to maintain your target.
I did this a few years back very consistently, 4-5 days per week. A retired pro who did 1 on 1 coaching for some high school kids used to give me pointers now and then, 6 months in I had a jump shot that was pretty damn good, better than I ever was when I played in high school. Ball handling wasn't too bad either.
