Well, being 5-9, myself, it's highly unlikely that I'd have any dunk stories -- but I do, and it's quite funny. However, its best told first by one of the witnesses, and as soon as Skander gets back in town, I'll let him tell you the particulars before commenting. (Mostly because it'll be fun to watch him try to type it while laughing.)
No, I can't dunk on a regulation rim. At my best, which was about 100 pounds ago, I could touch the rim, and even then, not easily. Playing basketball, for me, is about knowing and understanding the game and not about trying to exploit some sort of athletic skill that I don't have. Heck, one look at me, and you'll think "this guy can't play." But I've held my own over the years.
I will, however, match effective shooting ranges with anyone here. Not guarded, mind you - I'm a catch-and-shoot shooter and can't really generate my own shot off the dribble. And that should make it rather obvious that I'm a better fit for regular teammates or for organized basketball than I am for streetball.
Right now, however, I'm missing basketball. I ended up tearing up my knee on the ski trip - strained medial collateral ligament and a tear of the medial meniscus. The MCL healed quickly; the meniscus, which I also tore four years ago on the court (just before my FIRST ski trip), is healing VERY SLOWLY.
As for dirtly play, fouling on dunks, etc.? Hey - it's part of the game. Keep in mind that I'm the guy who defended Danny Fortson fouling Zarko Cabarkapa over on FanHome. (Got called everything but a white bear for doing it, too.) The rules say basketball is non-contact, and if you play me clean, I'll play you clean. Of course, that doesn't happen often, does it? Best to know how to defend against players throwing elbows, leading with shoulders, pushing off, hooking arms, etc. If I can learn something I can use from watching a Rick Mahorn, John Stockton, or Michael Cooper, then that helps make sure that it's not *ME* getting hurt by someone else. And those are probably the three guys I've learned the most from in terms of playing "dirty" while not going out there to hurt people. I learned footwork for guarding the post, as well as playing a person at their balance point by watching Mahorn. Stockton's arm-hook keeps me from taking hard elbows or getting pushed off. Michael Cooper was the best at burying a knee into a person's calf or thigh if they were trying to back you down.
