Since I posted in this thread, my college roomie rebuked me mightily and he has a point. Ming can touch the rim standing flat footed, so adding the 15-inch vertical leap, he can only block up to 11 feet, five inches -- not 12 feet as I speculated. Houston, we have a problem.
amazing response, stevel! really appreciate the effort you took to put up all that useful info! good for our understanding of rockets, and good for us bbsers too... used to be a high/long/triple jumper in HS, but i've lost nearly all my explosiveness through idleness in the past couple of years. i'll try to put a bit of your advice in the gym and check it out! thanks!
