That poster on the Jax sight was just making that stuff up. That is not even close to being true. Jordan was amazing, but there were several NBA players with higher verticals. For sure Dave Bing had a 52". What about the 5'7 guy who could dunk 3 balls? I forget his name, but he was around 48 or so. Darrel Griffith had 48+. David Thompson has at least a 48. I always heard MJ had a 45...similar but maybe an inch lower than Dominick Wilkins. I know it's splitting hairs, but irritates me when people just throw out bs like that. Jordan has amazing hops to go with his skills but I would guess he is not even top 8 all time in the NBA---and that excludes other sports.
Bottom line is that our new guy has so explosive skills.
