I was fast, faster than most. I was accurately (not a stopwatch, an actual computer timing system) timed at 4.57 in a 40. Granted, i was a sometimes 100, and always 200 and 400 sprinter, and not focusing on a short, pointless distance, but i could still move pretty quick. I am highly doubtful that either of these guys could run a professionally timed 40 faster than 4.4. Heath maybe... but i don't know many basketball players who are quick past 10 yds/10 meters. playing basketball, you don't even cover 40 yds if you run baseline to baseline! you have to train for speed, quickness for a few steps is innate (usually). Heath and dex were probably quick, but i doubt there were burners.
