I've had NBAFB for a few months now and I absolutely love it. Unique scoring with a great fan layout. Announcer is the same guy that voiced NBA Jam (Tim Kitzrow) for those with arcade nostalgia like me. I keep it at my office for the time being and it's become a regular lunchtime betting opportunity.
Your team doesn't matter - it's just a way to keep a bunch of individual high scores (so you can be the highest scorer when playing as The Bulls, for instance, and own that team with your initials).
Best ways to rack up points is to use Stadium Goodies modes to your advantage (left saucer shot). Get good at timing the backbox shot in the first mode (Crazy Bob's Concessions) and you can get a quick 18 points. The second Stadium Goodies mode (Hot Dog Mania) can be a bonanza if you can hit a lot of ramp shots quickly. Hot Dog Mania will give you 3 points on all ramps and it's on a timer that resets after every successful shot. The timer eventually starts counting down faster and faster, but a lot of points available in this mode. Mode 3 is Trivia and if you know your 90s NBA facts (who doesn't?) then it's an easy 10 points. Last mode is Egyptian soda and left and right ramp shots (which are quick and delivered right back to the flipper) are worth 3 points each.
There are a few different multiballs to trigger (SHOOT around multiball is probably the easiest, but is only a 2 ball multiball) and those obviously are a good way to boost score. If you can get all the way to Trophy multiball and shoot all the center ramp shots to earn a ring, you get to start all the modes again.
Here's the rules sheet from pinball.org that gives a little more in-depth detail (and all the answers to the trivia questions for super cheater cheatertons): http://pinball.org/rules/nbafastbreak.html
Would love to one day play the linked up version!
