i'd say at your stage of the game, don't worry about optimizing for your offense. until you are trying to make deep runs, it really doesn't matter how you fit to your offense, except somewhat for FB. defense matters but offense is much less custom.
in general, all offense in this game is best if it includes lots of 3 point shooting, which is heavily per, bh, and spd dependent. in motion, bh is slightly more valuable than other sets, but only slightly. bottom line, you want to get like 70/70/70 per/spd/bh guys, a couple, and have them do an awful lot of your scoring. this frees you up to focus on stuff like rebounding and defense in your other players.
