Bolton, I'm new to this as well, but I can tell you that whichever offense you pick, it will have it's own nuances. You will have to recruit with your offense in mind learn how to effectively gameplan based on what you've got. The Hoops 101 page gives a very basic overview of each offense and defense. Other can go more in-depth as to what works best.
You may want to look at your current roster to see what your young players are like who will be learning the new offense from the beginning...
