Well, at 5'9" as said before I am the king of dunks as long as they include some sort of pastry and coffee. Seriously, my basketball playing days ended many years ago with a totally exploded right knee. both the medial colateral and anterior cruciate ligiment torn beyond healing and replaced with gortex grafts, medial meniscus cartilage torn, and a petella (kneecap) that is now porcelein after being broken, by the orthopedists count, into 26 pieces. Did it in a mountain bike race (of course) and it took me close to a year to learn how to walk right afterward. Same surgeon that repaired my knee had done all the surgery on Danny Manning so I knew I was in good hands.
Not that in my hey day did I ever have ashot at dunking a basketball, you guys think white guys can't jump, you see and Apache Indian try it. my specialty was the mid range jumper and suffocating defense. pretty good passer too. Didn't have the quicks off the dribble so I was never able to dazzle anyone, I was just a role player. Street ball was too fast and lethal where I grew up, someone my size without the skills these cats had rarely attempted to get in there, the style on my block was Bill Lambeer physical and broken bones were not uncommon on the blacktop.
So now I just stick to my mountian bike and training like crazy to stay in shape so all my injuries over the years don't turn me into a crippled old man before my time. I may not dunk, but no one I know my age, including anyone here on this board, can keep up with me on a mountain bike.
